I liked a girl in the past. A bully also liked her. So I've lost hope about her. Now I also like guys. Am I really gay or its just because I lost hope? Help me please.

Some people believe that sexuality can change according to what happens in our life, but it's simply something we are born with and we learn to discover with time. Maybe what happened simply helped you discover other aspects of yourself. If you like guys and girls, that would mean you are bisexual, not gay. Living in an heteronormative world, it's very frequent for people to need more time to find out that they're not straight. Probably that's what happened to you: you've always acknowledged the part of yourself that likes girls, and it took more time to find out you can also be attracted to guys. Discovering your bisexuality can be confusing at first, but with time, working on your self-acceptance, also getting support if you need, you can come to terms with your sexuality and accept it as a natural part of yourself!
