I’m losing myself

Idk what’s happened to me I used to know what I am and what I always wanted rn I’m at a complete list of myself I let things happen that I usually wouldn’t I tend no to know when to stop anymore. In school I’ve never let my glade slip it’s always perfect A’s now it’s slipping. I feel like I’m rebelling against myself. I don’t know how what happened but I don’t like it. It effecting my relationships. It’s like I don’t know who I am.

I don’t know how to bring myself back.
