Venting parents ruined my ability to ask for help

[sunny]

when i was younger like 10-11-12-13 those ages i would frequently ask for help I just had started experiencing SIDS and i was harming myself. I didn't want to feel like that anymore so i asked for help from my parents and i got a nod basically and that's it so now I don't talk about my mental health to trusted people because of how i was shut out when i was younger it just feels WRONG to talk about
and yk whats even more messed up my sister attempted suicide and the whole world stopped but when i had the same problems no one took me seriously
ik ive ranted ab this before but randomly i remember why i have issues asking for help and why i suppress my emotions

anyone else relate?
