I'm depressed and have agoraphobia how do i overcome this?

I'm bad with directions and its embarrassing cos i'm 21 aswell. I have to go to this mental health place and i tried asking for help off my doctor to get a taxi to the other side of town and he said he can't do it and now i've had my disability stopped for not attending before, but its a struggle and i also have a disturbed sleep pattern and can't stop sleeping during the day. I blame a certain relative cos i was homeschooled by them and never learnt anything and never went out and now i feel suicidal cos of it. I'd be happy if there was someone there to make me happy like a GF or something who can identify with it, but i'm very insecure aswell what do i do?
