I'm 17 years old and I have vaginismus. What can I do!

I am 17 years old and have vaginismus, I was never able to engage in any type of vaginal penetration. Even before I would attempt to touch there, my insides would instantly tighten up and my brain would tell me it’s going to hurt. I’ve told my Gyno that I believe I have this problem, and he just gave me numbers to psychiatrists and I’m afraid to go and just want to fix this on my own some how. I can’t afford a dilator kit as of right now either…I feel hopeless. Please help.
