Severe anxiety about moving/my future

I'm currently 8 months pregnant and living at home, the plan all along has been for me to move in with my boyfriend with the baby once he is born. The problem is that moving causes me severe anxiety, it leads to this whole depression/anxiety/OCD cycle and usually takes me about two years to fully adjust and be happy in the new place. It's been that way my entire life. Change is hard for me. It doesn't help that I'll be an hour away from the city I love with all my friends and family. I'm really scared that this move is going to set me off which is the last thing I need with a new baby. I love my boyfriend and would love to live with him and have our family together but due to my anxiety everything in me is begging to run from the situation. The panic is so strong it's hard to be rational about it. Has anyone dealt with this? Any ideas on how to help it?
