Sensitive feelings

I'm still so bothered by the past occurrences that no amount of distraction could make me forget, i keep remembering, and it makes my heart ache. Last night was so fun and i felt so much thrill and joy but now i just feel so sad and hurt, i don't know what else to do. Usually when there's a bad memory i could only do nothing but make distractions and wish for the best that I'd hopefully forget about it, or atleast the bad memories effect on me lessens to the point i could careless about it anymore, but now i just straight up want to forget it, i want to forget them, i want to forget everything. It's so bothersome. I wish this just stops already.
