I understand. You don't have to approach police at all, but it's only if you feel like it would be a reasonable and beneficial option for you at this stage. Of course, you know your circumstances best and what you feel comfortable doing and not doing, so it's entirely your choice.
I would also like to mention something else that I didn't in my last reply. It's a lot easier said than done, I know, but try not to dwell on the things that she has done in the past. It appears to me that your former "friend" has recognised what they can do to make you feel this way, and they enjoy doing so. You could start with repeating a few positive affirmations, like "I am more than the judgements of others" or "I will not allow her to control my thoughts", and you may find that the more you start to say or think things like this, they can become true for you. This is quite a minor change, but it can be quite effective over a long time.
I'd also like to advocate for the use of journalling or writing private letters that aren't meant for sending to people. It can be so incredibly therapeutic to write out exactly how somebody's behaviour is making you feel, even with no intent of the person reading it. It's one sure way to validate your feelings quickly and to get down to the root of what's causing you distress.
I'm so glad to hear that you're finding some comfort in the forums, that's all we can hope for. As always, stay safe and take care.
