I Burned Myself Again

22f. I ended toxic relationship a long time ago but I got back to him sometimes. I did again last night and end up feeling like a piece of shit. Got back home and burned myself with ice again which haven't done for a long time either. He has a new gf so I feel extra shitty even though he always cheats no matter what anyway. I should just sleep and start over in the morning but maybe I might keep burning.
