Want to improve my mental state.

- On the other day I went to one hospital with my wife as she is pregnant, there was too much crowd there and not sure I started feeling as if I will faint and started sweating, I was scared in the crowd. I feel most of the time that I will faint when too many people around me. - Sometimes I can't speak to a person by seeing in their eyes for long time because again I start feeling that I might faint talk to them for long time. This is only happens when I think about fainting if I don't think about it then everything is normal. - I am not able to make friends because I think I won't be able sustain it for long as I don't like to go to any social function s of friends and family. - I tried meditation and yoga for sometimes but it did not helped because I started analysing everything and started thinking if one has to die then why we are struggling? - I always in worry what if I lose my parents? Coz my parents and my wife are my best friends. Please help me to enjoy my life.
