Sometimes I don't think there is any answer to why depression strikes a certain person or when it does. I was in my thirties when it struck me. One day I was fine, happy and outgoing and the next day I couldn't quit crying, had a horrible headache and nausea. Went to the doctor because I thought I had the flu or something. When he told I was depressed I was shocked. I have battled depression every since. I wanted to withdraw from everyone, but could manage around strangers easier. They were easier to convince I was okay because they didn't know me a well.

I would suggest seeing a professional and see if they can help. I wish you luck. Check out PC. It's a great place for support and making friends.
