Can’t leave the house 🥺 anxiety related

So I’m diagnosed with agoraphobia and derealization/depersonalization and anxiety in general . And no one in my family seems to believe me or what I go through is real. So my mom just constantly pushes me on getting out of the house and I get she’s worried but that just makes me more anxious . And I live in a rural area and have no money or insurance so I can’t really get a therapist. Idk what to do it’s gotten to bad I basically have panic attacks where things don’t feel real and it’s super bad in cars so I avoid it . :(
