okay okay I need!!!!! advice

my fp cut me off in November of 2024 after saying he promised he would stay if I had an emergency (my parents had done really horrible things to me and cps was involved. they found them them innocent.) and I've been an absolute train wreck ever since

I lost 90% of my friends, I haven't brushed my teeth in ages, my grades are falling and I'm risking getting kicked out of an honors society, and now I still cant function without him even though he hates me now

wtf do I do random teenagers on the internet...... what do I do!!!!!!!!!!!!
