Hey man, sorry to hear you relapsed. Good that you’re identifying trigger times and have put a restraint on your phone.
I have experienced all the things you described. I was an awkward kid and that led to much isolation. Because my peers recognized that I was isolated, it was hard to make friends because they didn’t want to be isolated too, enter rejection. This led to hurt for me. This would play out further and more graphically in my adolescent years. Even sometimes as an adult I feel isolated. I sit in a cube farm with 11 other guys and they rarely interact with me, even if I say good morning. I hear them make plans after work together, it is rare that they invite me.
Reading through some of your old posts… You’re in a tough situation my friend, with no meetings in your area. SA does have phone meetings though, something to consider. If you don’t have access to SA literature, if be happy to mail you some if you’re comfortable PMing me your address. And, looking at your profile, I’m guessing you don’t visit many of the other threads on this forum. I recommend trying them. The “substance” we are addicted to may differ, but our struggles are very much the same. Feelings of defeat, hopelessness, and isolation are common among us.
