i am a nuisance to my parents

i believe i need therapy, because of my multiple different mental health struggles including heavy social anxiety and a mild ed, that i am trying to control. however, whenever i reach out to my caretakers they refuse to find me a therapist and, of course, pay for treatment. they do not take me seriously whatsoever and try to make me feel guilty for making them upset every time i bring it up. i do not have anyone else to talk to, and don't really know what to do anymore
