Depression. Goes in different way.

Unable to talk with anyone. Always in full mood. When I tried to read any books I'm unable to read them. Getting very much fear. Getting full tension. I always with fear only. So many people watch me like I'm a silly person. My head always be like with full weight. always getting headache. No peace for me at home and outside. I think I can't live without any others support even a single day. My heartbeat always very fast which tends to fear and tension for me. 3 years back I tried to suicide. But there is no interest for me to suicide. Most of the times my mind will be in block mode. I can't able to listen others what they are saying. Because my thoughts goes in different way. I can't able to listen classes concentrated. Without my knowledge my thoughts goes in different way. Thank you...!!!
