The best way is to start doing things for yourself...don't try doing too much on your own because that will only overwhelm you. Just take little steps.

I used to be exactly the same way...and ended up having to be out of a relationship for a period of time...on my own. That's actually how I learned some of my independence. No, I'm not fully dependent, but I am somewhat dependent now.

Do you have a safety plan for when you are away from your boyfriend? That would probably be the best thing to develop first. Just basically things to keep you busy like cleaning, playing games online, writing, etc. That's actually how I started out. I started doing things on my own when I was upset. And the more I did these things, the more they worked for me.

Hang in there...you can conquer this!
