"Hi, It's me. I'm the problem it's me."

Idk when it started but I always feel like everything I do is not enough. I did achieve a lot of things especially in school but I still feel like it's not enough that I could do more and do so much better than that. I have this mindset that I want to be able to do everything or to be good at everything. We're about to have a program in our school and AGAIN they're planning to make me the host because of my loud voice and my happy-go-lucky facade that may entertain the viewers and that made me question myself "Is that all I could ever be? A host? Again?" when my friends get to sing and dance : ( I felt down. After that it made me feel insecure tho I'm fully aware that every people is different and we have our own talents but me? I feel like I should be good at everything and I can't accept the fact that I can't (I mean yeah sure someone can be good at everything) Idk if this is valid or it's indeed a me problem that I have to fix. I'm so tired of feeling this way:( I still have so much to say/vent but I feel like it's nonsense.
NOTE: I excuse my terrible english, it's not my first language but I just want to express how I feel and I don't have someone to vent with.
