lack of confidence and chronic hair falling

Hi iam Madan m/26 ,iam studying my PG,

My main suffering is i have antagonsim within my self,especially when iam involved in speech,or any stressful studies,lack of confidence in speaking,and all the activities,and concetration difficulty in studies, i feel like i have two personalities one for stressful activities to manage and other to be in relaxed state. and i have vertigo towards right side when i stand or walk after i had roadside accident

iam overweight, and i have chronic hair falling, for past 5years,partial baldness in frontal scalp area, when i tensed more or if i have stress to study more my hair falling is more, i feel very sad when there is more hair falling,i have pain in my left side testicles also,

At the age of 17 i took medicines for depression from a psychiatrist,later due to increase in weight i went to a homeopath
My hairfalling actually started when i was 20years old,took treatment from a homeopath for obesity and for broadening of face, i had chronic pain in Maxillary region, later it was diagnosed as Maxillary sinusitis,by a allopathic physician and i took some antibiotics, Now i dont have pain in maxillary region,but i used to get rarely,

I feel better in hot climate,iam easily offended,little arguing,very lazy,aversion to mental work like studies,and work,iam afraid of crackers sound,and aversed to speak more also.

i feel well comfort with my families and my friends, but i dont believe myself,

i crave for non vegeterian more, i like salt item more rather than sweets,

i drink more water,i like jucies and cold drinks more,
rather than coffee and tea,

in my family my grandmother,uncle had diabetes,thats it,and my father has only partial baldness ,I took medicines, Anacardium 200 for my antagonism within my self, after taking i feel better, but after taking it i got gastric regurgitation and heart bun, so iam unable to take that, I have also taken Arnica 30c as a wet preparation for my hair falling, according to Mr,Joe de livera, but it helped me little only,and other homeo medicine like Gelsemium,and Aurumetallicum, also i have taken which helped me to cope up with my stressful mood,But i still feel vertigo towards rightside and antagonism within myself, is there any medicine to cure my partial baldness and a remedy similar in action like anacardium,
can any Doctors here provide me a good remedy and guidance,I would be glad to hear any response
