I think don’t worry about her for now, she’s asked you not to, but worry about yourself.
Sit with your feelings a bit. Try and articulate how you feel precisely to yourself (ie, I feel really hurt and unloved - this doesn’t have to be logical or proportional, you just need to identify clearly how you’re feeling amid thw swirl of ‘agh! Agh! This hurts! I don’t like it!’).
Then think: okay, well, I feel a bit wounded and panicky and horrible inside, but that’s okay, I’m just going to sit with that for a bit and really feel it, be nice to myself with a cuppa. Then I might have a think about WHY I feel like that. And try and disentangle some of the emotional threads.
And don’t forget the 72 hour rule! MOST emotional responses have settled down a bit after three days, you just have to ride that initial pain out. Then you can reflect from a more calm perspective.
People, especially recovering addicts, can be terrified so much of ‘feeling’ the pain that they do anything to make it better or make it go away. It’s okay, it’s fine to feel really very sad and hurt that your friend pushed you away, while also respecting her need to be at a distance from you.
It’s also extremely common for addicts to hurt and push loved ones away. People who have not had close relationships with addicts often don’t realise how incredibly complex and tangled and toxic those pushes and pulls are. Take care of yourself, love.
