Daydreamer and hair puller......

Im a catholic and I think this a good place to share this Im not sure if my question will be answered since everyone is talking about Trump right now but its worth a shot. I constantly pull out my eyelashes to honestly cope, Im a 17 year old girl and my school life has been so stressful. Ive been accepted into two unis but Im not sure if I can maintain the early acceptance for them. My hair pulling was never this bad but now I have no eyelashes its fully bald the whole length.... whenever I want to do it I think of God and how I keep saying I wont do it but I never listen. I feel so guilty afterwards but the pain is satisfying for me. I pray about it but I just cant seem to stop.... As for my daydreaming its even worse. Ive been daydreaming for as long as I can remember seriously of just me being prettier, thinner, smarter and having that dream life. Ive incorporated Jesus and praying into that reality of mine so its less bad but its still not good. I used to be a 90s student and now Im struggling because all I do is daydream. I cannot stop and I keep praying about it and cannot stop. Im supposed to be studying for my diplomas but here I am pulling my hair and daydreaming. Anyone have advice?? And please dont be harsh I quite literally cannot take the constant disappointment I feel from everyone anymore.
