I did it.

I did it!  I just broke it off with the BF.  I am terrified.  I know its right but I don't want to start having all those feelings again.  Anxiousness, dependency, where is he, i love him, who is he with, what is he doing, thinking about him constantly!  
He doesn't respect me.  He doesn't appreciate me.  He doesn't deserve me and I deserve way more than him.  I can do it this time for sure.  I have to.  How though?  How will I get through this?  Oh god I hope I will be ok............
