Depression, Brain fog , gastrointestinal issues

I am male 28 years of age

I first fell into depression in 2018 by wrongly thinking that I have hiv by looking symptoms online.I was living under chronic stress and dipression thinking that my life is ruined. I lost all my muscles and become a skinny fat guy because of chronic stress I didnt go for testing, Because I was sure that I had hiv ,But after 2 and half year i decided to test and to my surprise i was hiv negative. I thought that from now on everything will be fine , But I was wrong I was unable to come out of depression and chronic mental stress. I was now having continuous running thoughts in mind, was unable to think Clearly , unable to sleep due to running thought in mind . Then i developed eczema all over my hands and very bad itching. I went to a dermatologist, he prescribed me antifungal but they did nothing. After months of pain and sleepless night . I decided to stop eating wheat (after looking online) To my surprise my eczema went away within a week . But there was no releif in other symptoms. I was unable to gain a single pound of muscle, no matter how many calories i eat. When I went to sleep after an hour I wake up due to continuous running thoughts in my mind like a movie . I was having digestive issues as well my poop color used to be stark light yellow. My cognitive ability declined greatly. I used to be very bright student. But now I was unable to do simple calculation. Unable to think Clearly. I visited a psychiatrist, I told him about my running thoughts anxiety and feeling negative, He diagnosed me with ocd and dipression and prescribed Ssri and other medicine. Now I was able to sleep properly all my running thoughts went away . I started to feel motivated. But after a month or so everything reversed I was constipated my stool again turned light yellow and i became more depressed i told him about this he changed medicines but things for me didnt change. So I decided to stop medicines. After stopping medicine my running thoughts become very bad . I was thinking and thinking negative about very trivial matters my anxiety went off the roof . Then i became a zombie like. I was having no emotions, no positive no negative. And then anxiety came back , i was switching between these two states. Sometime I got constipated some time I had loose stool ( not watery stool) a stool without no form. My hair started falling all over the heads uniformly including the sides too. I visited a hair specialist he told me it is telogen effluvium , i didnt take medicine by thinking that when my mental issues gone my hair will return. I started to think that there is no cure for this and I have to live like this all my life. But one day after reading online about gut- brain axis i decided to try probiotic and removed legumes , chickpea and millet from my diet two month back . My brain fog improved to a extent and i was able to sleep for whole night for couple of days, my muscles started to get in old shape like body has a memory, i was seeing visible changes on my chest muscles But then probiotic made me constipated very badly . I tried different strains after a week or so evey strain made me constipated and weird side-effect like double vision at night. I last took probiotic 5 days ago. Now I eat only rice with green legumes called khichdi in india. But yesterday I decided to eat sorgum millet , after couple of hours eating my brain fog returned.I got nightfall. I do not have sex libido. But today I didnt eat sorgum my brain fog improved . But I am like a zombie now. I have no emotions either positive or negative not feeling motivated, not able to sleep at night due to running thoughts. I dont feel thoughts at all they do not make me positive or negative. I have no emotion now . I somewhat can think Clearly but no emotions. I eat khichdi and some fruits only. Please help me. I cant describe due to my low cognitive ability now , that i how much I am suffering. Chronic stress and dipression messed up my digestive system. I think I have leaky gut issues as well. No sex libido due to dipression.What should I do please help .
