homeopathic remedies suggestions please for anxiety and panic attacks

I am a 33 year-old female, and a teacher, who suffered what I think is a major panic attack four days ago. The big muscle in my upper legs was shaking, as well as my hands a little bit, I was gasping for air, then I couldn't stop crying. It lasted for at least ten minutes. My whole body was affected, it was like I had been in a car accident, and the feeling lasted for almost two days. What brought it on - I had been sick for two weeks, I recently moved in with my boyfriend and I am having problems adapting, I hadn't been sleeping very well, I had lost some weight, my sister had been threatening to commit suicide, two students put something in my drink when I wasn't looking the day before, and when the attack happened I had just arrived late for work and then was told not to be late by my boss and then handed a nasty letter from the parent of one of my students.

I have only had three panic attacks total in my life. One happened two years ago after I broke up with a fiance (that happened at work as well) and another when I was criticized by a boss around 12 years ago.

For the past two years, when I even think about something stressful, I feel a wave of nausea go through my body, sometimes to the point where I need to sit down.

Throughout my life I have been afraid of large groups of people and as a child I would usually just wait outside the school doors during recess and not play with anyone.

My job is difficult, I teach an unpopular 2nd language which parents and students do not support for political reasons, and just because they don't want to be bothered learning something difficult. I feel like all the teachers in my school think I am doing a bad job, a couple have even told me so.

I am always late for everything, I have been like this since childhood, and I still am always late.

I don't have any close friends other than my dog and my fiance, and he is confused about my recent problems so is being distant.

Please suggest some homeopathic remedies. I greatly appreciate it.
