Change is scary

Even though I'm going through this training, I still have doubts and worry that I'm not going to be able to keep it up. I worry about relapse, the stress of going on to new things, making new supports, friends. There seems to be this lingering ghost, hovering in the back of my mind saying what if you can't do it, what are you going to do? I know I've worked so hard over the last 8 years, and learned a lot of tools and skills, my WRAP plan, but change is still scary to me sometimes. Does anyone else feel like this. I think a little bit too much sometimes, maybe it's just me.
