What should I do? I'm still in the closet.
I'm sorry that you are going through that. Why are you still in the closet?
Because of the fear and shame I feel.
It is hard to deal with feelings of fear and shame but you should do something about it. Like talk to someone so that you don't have to hide who you are and can be happier.
Why am I hiding that I'm gay?
Hiding your sexuality can cause you a lot of stress and inner turmoil. You should seek out a support group to help you lose the fear of coming out.
