I dreamed about finally taking my ex to court

So I dated someone with (at the time undiagnosed) quiet bpd for almost 3 years at the age of 17 to 21, the first half I dated a man and then they transitioned to a trans woman. 7 months ago I broke up with her and I'm now 6 months no contact.

Unlike many of the stories here, she was never verbally abusive or the relationship wasn't completly toxic.

Short long story, it was love bombing, Idealization, the progressive bigger small tasks, the highs and lows moods, not being able to control her emotions, unstable sense of self, emotional manipulation, gambling addiction between many others. She ended up diagnosed with bpd and severe depression, gained a big debt through gambling, got hospitalized twice and try to khs.

She's been harrasing me since the break up, messaged me through all my social media and through differents phone numbers, calling to my work, harassing my friends, sending me letters, etc. I just blocked her and tell her mom.

Two days ago, she sent to my job a letter, trying to convince me (and her) that she's got better and please contact her, using everything I once said to manipulate me, that she wants to be friends, etc. I contact her mom and she told me she didn't know what else to do and that maybe I should go to the police. I know they are not going to do anything because she's not threatening my self being, so I've been scared of waiting for it.

Today I dreamed that she kidnapped me and took me to a weird place, I was so fucking scared of dying but I knew that this was finally the end of it, she's 6.2 and Im 5.5, she's much bigger that me and at times I used to realize that she could do whatever she pleases with me. In the dream I could scape and went to the police, they still didn't want to take my story but I kept insisting, I woke up when I was telling the last part because I realize that it didn't happened and I was in fact dreaming.

I feel like I'm driving insane, always anxious and scared, I'm trying to find a therapist but I can't really afford it yet. I can't afford a lawyer or a court case neither, I don't know what to think anymore.

if someone read this thank u, and every advice will be thankfully welcome.
