I Have the Urge to Self Injure

I havent in a very very long time. Im not sure what triggered it i was having a nice relaxing day ive read, studied, played games but randomly it just hit and ive been trying so so hard not to since than but i feel like im losing. i feel so stupid and so pathetic i should be past this by now i dont know what triggered it. all i can think about is swallowing some pills, burning myself, biting down hard enough to bleed anything just to make this feeling go away. I keep trying to distract myself but nothing is helping at all. ugh this just makes me feel even worse to be honest.
