Binged, Overthinking (need help)

Hi, I just ended my 13 day streak 3 days ago and I PMO'ed on the first and second days 2 times and MO'ed 2 times on the third day. My OCD is getting worse and worse to the point I try to hurt myself to stop it. My brain won't let me start NoFap again until I start with a NoBinge. Like it keeps bugging me to abstain for some time then relapse once then I can go for NoFap again so I can have a non-binged start. Should I like abstain for 7 days, relapse once then start over to get this feeling out of my head? I'm only 15 years old and it's really hard for me, I've been trying to reach 90 days for 6 months now but 13 days was my longest.
