Feeling Hopeless and Trapped in a Mental Hole

I feel so hopeless , I don’t know what to do. I feel so mentally stuck and trapped in a hole. I feel no hope. I feel so tired of trying. I’m telling myself I need rest but I feel like I’ve been resting for too long but truly I’ve never gave myself the chance too. I feel like I want to give up , I can’t keep doing this. I feel like I need someone to help me out of this darkness. I feel like time is crushing me , I’m 20 but I feel that I’m so old. That I don’t know what path to take. Everything I do feels wrong. I can’t keep feeling like this. I’m going crazy, I just don’t know what to do. Is anyone dealing with something similar
