I want to cut Again

Okay so I haven’t cut in about 5/6 months and I really want to cut again. I don’t know why but it calms me. It makes me numb to the pain around me. And recently I’ve been getting these urges to cut again. I just want to grab a blade, or broken glass, or a knife, or anything remotely sharp that will pierce my skin and make me bleed. I’ve been getting to the point where I’ll start shaking and can’t stop. Or I can’t eat. Or I can’t sleep/ wake up. But the problem is, cutting doesn’t do much anymore. I’ve become numb to the pain. Last time I cut, I cut 40 time on my leg continuously/back to back. I’ve been wearing hair ties on my wrist and popping them and hitting my veins and that helps a little, bit t it’s not enough. I really don’t know what to do at this point.
