I hope someone can help me out because I'm having the worst week of my life. Apart from experiencing incredible anxiety and depression, I constantly miss my old self. Because my problems started at the age of 21 and have been going on for 5 years. The other problem is that I am constantly comparing myself to other people. By constantly examining people, I question whether they are unhappy too. When I see a happy person on the street, I get even more depressed. 

Do you think it's possible for me to go back to my old self? I have been on medication for 5 years and now I feel very hopeless. Please give me hope. Please tell me that I can be happy like other people. I am in such a state that I cannot go to school, I am in a constant state of panic.

I feel alone in this. It seems as if no one experiences this degree of anxiety. It's like that's just me and no one understands me. I miss my life before my anxiety disorder so much
