Why am I so bad at life? I hate who am as a person. All my friends treat me like a dumb. I can't stand life and for some reason I am deeply in love with girls. What can I do?

I am so sorry you feel this way; don't let how others treat you/ say about you effect you! I know you are strong! I understand how it can feel to be "bad" at life, but it helps to just see life as a journey, and there is no wrong or right way to live! Just existing, is already proving that you are doing the best you can. I deal with lack of motivation, and it's easy to fall into thinking I can't do anything right, but I, and I know you, have that inner strength to fight on! Ways I have helped myself is to try figuring out what my passion is and find ways to do what I want, without hurting others. I hope you find a welcoming community here.
