Hi. If you have chosen not to contact this person because it would hurt you or them in some way, maybe it would be a good idea to talk to someone else about WHY you feel like you want to in the first place? Sometimes I just turn my phone off and put it in the highest cupboard in the kitchen. I have to get a step stool out to reach it. That helps limit the number of times I reach for the phone.

You could put a description next to that persons contact details saying something like DO NOT CALL, or IF YOU CALL BAD THINGS WILL HAPPEN. Something like that. Or erase their details completely.

Do you have that person on social media? Maybe you need a break from certain pages for a bit, at least until you feel better. I turn into a mega cyber stalker when I "need" to know... so the first time I got hit wtih a major episode i got my brother to block a few web pages until I got over it. That one worked wonders.

As you have probably guessed, I have a masters in avoiding people I shouldnt talk to. If you need more ideas, or if you just want to talk, let me know.
