Heart Palpitations - I'm pretty sure I screwed up with my use of the Homeopathic remedies

I am new here and am looking for some guidance.

I know very little about homeopathy and, I think I have made some gross mistakes before I joined this forum and realized, after reading a lot of posts, that I am truly an idiot.

I did not know that one cannot take several remedies at a time until now. Since there are combination products on the market (like ‘Anxiety Relief’, etc)… I erroneously assumed that the remedies could be taken in conjunction with each other. I only waited 30 minutes between them. Amazingly, I think something did help, but I know not which one it was. I will describe how I took them at the end of this post, but I took Prunus Virg, Lachesis Muta, China, and Rescue Remedy
I am a widowed 58 yr old female and have been having heart palpitations for about 2-3 years now. They were very few and far between at 1st, but now, I get them a lot; usually several x’s a day for 3 or 4 days at a time. I have high B/P and I think when either that or my pulse is elevated that it precipitates the palpitations. In the past I was prescribed the medicine, Vioxx®, and I took it for some time before it was withdrawn from the market and I often wonder if it caused my palpitations.
In the beginning I could usually stop the palpitations by taking a half of an Atenolol (25 mg) & a half of a Xanax (0.25 mg). I noticed a long time ago that anxiety about the palps led to panic and that made them worse… thus the Atenolol & Xanax (at the time Rx’d by my family Dr. who I have come to believe doesn’t have a clue). I didn’t want to keep on with the Xanax and started looking for other answers. I have had some success by adding to my present supplement regimen; Omega 3’s (fish oil), magnesium, CoQ10, L-carnitine, Nattokinase & L-arginine. These I added to my present program of numerous supplements. I also added an Herbal anxiety product. I saw less episodes of palpitations after taking these nutrients for about 2 months… but they didn’t stop.
Whenever I feel even a small twinge of anything that even resembles a palpitation, I usually work myself up into such a state of panic and anxiety that they usually get much worse. I think I do have some cardiac involvement but I have no medical insurance at this time and I have not had a cardiac workup. Also, sometimes when I am really in a panic attack I get short of breath and a little dizzy. Also I always feel better if I lie down on my left side almost on my stomach (I know that is NOT one of the indications for Lachesis but it still helps).
I have other health issues also, obesity (I am losing about 2 lbs/week now), and severe debilitating arthritis in my knees. I recently got disability because I have absolutely no cartilage left in my knees and it is bone against bone and I cannot walk anymore. It is a supreme effort for me to go from the bedroom to the bathroom. I have become very inactive over the past 8 months and now I fear I will not be able to walk again because if you don’t use it you lose it. Because I am receiving Social Security Disability before the usual age of retirement, I have a 1 year waiting period before I will qualify for medical coverage. I might get knee replacements at that time if I can. I have worked all my life up until a year ago and I am really suffering from the inactivity. I am an LPN and I most recently worked in Mental Health and Drug Addictions. I loved my job and I stayed at it until I was unable to walk any more.
My adult disabled son lives with me. He is a Schizophrenic, but is controlled on medication. He helps me a lot in day to day activities and household chores. We also share our home with 3 cats and 3 birds and we love them as family members. They are my children, too.
If I ever get myself straightened out I would like to train in Homeopathy. I am a pretty good Herbalist and I have always aspired to be a “Healer” instead of a “nurse”. I hope I am not too old to learn more and be of some help to someone.
I am an avid reader of both fiction and nonfiction and I also spend a lot of time researching topics on the internet… there are so many interesting things in the world. My husband died in 2001 and I still miss him terribly, although I have always been very independent. I miss the closeness, affection, and most of all the companionship. I am a typical Libra in that I balance everything and go back and forth when deciding issues. I am very outraged at the injustices and cruelties in the world and I often find myself upset and crying over abuse done to animals. I truly believe that ALL life is sacred and that ‘humans’ are not the only game on the block. I am absolutely horrified at some of the things that go on in the world. Sometimes I over-simplify things and wish that ALL of Creation could live in Peace, Harmony and Balance.
I wonder if somebody could straighten me out on this homeopathic mess I’ve made. The palpitations actually did stop every time I took the remedies.
My palpitations usually start late at night
I started out by taking 10 drops of 12C Prunus Virg in about 12-15 cc of water.
After 30 minutes I took 6 pellets of Lachesis Muta, 6C (the palps were just starting to slow down after that)
After another 30 minutes I took 6 pellets of Cinchona Off, 6C
The palpitations were totally gone after about 2 hours.
During the day I took Rescue Remedy.
That was the quickest I ever got rid of them. They stayed gone for almost 3 days; then I started getting some faint palps and I did the routine again. Again they went away.
Tonight I got palps and went through the routine again… again they went away.
THEN I joined this forum and started reading and reading and reading….. THAT is when I realized that I was an idiot!
I hope I didn’t write too much.
Peace.
