My mind is constantly racing

For a while i've been unable to go to sleep, my mind races with toughts and i cant fall asleep and when i do sleep its restless. This happens to me during the day too unless I'm busy or blasting music in my headphones but i cant sleep with my headphones on because they're too big and it would make my ears ache. I cant keep going like this, its preventing me from resting and stressing me during the day. I was told by my therapist i might have an anxiety disorder but she cant tell me for certain bc in my country a therapist can only do as much as talk to u while a psyhologist can give a diagnosis and offer medicine. So my therapist put it as a possibility, but i haven't gone to therapy since last year because i cant afford it, I've been going trough a program with free therapy but they closed it. Is there anything i can do regarding my racing thoughts?
