<human>: Can you succinctly summarize the text in 1-3 sentences?

I lived with my mother until she kicked me out when I was 18. During this time I was nothing but a problem for her. I completely failed school and college (I live in Scotland, college is not university here. It's sort of like a stepping stone for those who didn't do well enough in school to go straight to university). I had major anger issues, enough for her to call the police on me at least 5 times. They would come out to the house and tell me to calm down. I hated her so much during my adolescence and on the surface she seemed to hate me too. No wonder to be honest, I'd fucking hate me too but unfortunately she wasn't big enough to whack me in the face which is exactly what I needed. I needed my dad. I was disobedient, wild, insecure and I didn't care about anything. And my mum had no control whatsoever.

Which brings me to now. I feel like the only way I'll manage to attain any sort of education is if I'm financially and mentally stable. Right now I have neither so I've planned to move back in with my mother. If I move back in with her I'll be financially comfortable because my monthly outgoings will be cut significantly. Once that happens I can begin to rebuild my dying relationship with my partner which hopefully will bring me some mental stability.

------------------

Here's my proposal:

1. I will pay for everything I use so that her outgoings will not increase.

2. I will suppress my anger, moreover I will attend therapy.

3. I will study full-time including at home and will attend college when required.

4. I will pass college.

5. I will work part-time to support myself and my lifestyle.

I have asked her before but her answer was no. I expect if I lay out my proposal that she may consider. What else should I offer? You have to understand that this is my last resort. And by last I mean ultimatum. If this falls through I won't survive myself.

**Any questions welcome. I have left a LOT out in order to be brief.
<bot>: Screwed up growing up living with my mum. Lived on my own for 3 years but need to move back in for stability in order to educate/better myself. How can I convince her to allow me?
