should i get therapy?

throwaway account: i’m 19 (f) years old, i’ve been through some shit. i have a father with aspd and a mother who i assume has bipolar disorder but has never been diagnosed. i’ve experienced a plethora of issues myself, whether it be related to them or not. as a kid, for custody reasons i was forced into therapy and only would ever be probed to talk about my dad, so i’ve been sort of against therapy personally for a long time as it never helped. i’ve been considering going back lately but between going back and forth between school and home im not sure what my best option would be. i don’t wanna use better help as i’ve heard bad things, but i don’t want to go somewhere while im home for the summer and then leave that once i go back to school for the fall. i’ve gotten by so far myself, but things aren’t great and never have been. i hate self-diagnosing but my symptoms all align with bpd. whatever it may be, what should i do?
