Panic attacks, lost confidence,

I have had 3 panic attacks with same dream continuously within 2-3 months. Lost interest in everything. I feel like quitting. When I was 16 yrs old, my mom and dad had court case against each other, since then my mind is disturbed. I was even tried to kill by my father twice at that time. Now I'm 23. Due to this incident, I have lost all my relatives. No one is close enough to talk and discuss my problems. I feel like I'm burden on everyone. No one supports me no matter whatever it is. I completed my education from the UK by taking bank loan, father didn't paid a single ruppe towards my education. I don't feel like hanging out with friends. I have became so shy towards females that I start freeze when I have conversation with them. I have lost confidence in everything. During my stay in UK I was quite happy to stay by myself. Since I came back I feel negativity in everything. I have international student of the year certificate and now I don't feel like studying at all. Need some help
