Should I go with my gut feeling?

I'm having so many problems with my family, and have been for 3 years now. I feel as though they just dont want me anymore. So, my plan is,.for this summer,.I plan on movin in with one of my g/f's and her family. This would be a big step for me because I've never lived out of state, and especially with one of my good friends. Do you think I should go ahead with this plan?
