<human>: I started doing drugs when I was 14, mainly as I moved in circles with users. I've never been completely dependent, but spent my teenage years on the road between friends houses up until I left for University (where I subsequently cohabited with a now ex girlfriend and pretty much dropped out).

I was allowed to return to London, my home city, to live with my parents and little brothers while I worked full time in a call center. The workload was pretty high, so I'd compensate by smoking when I got in, which usually ended up in me crashing out in front of my computer, either coding or listening to music, pretty early. The weed never effected my actions; in fact if I hadn't smoked I may have just watched TV more and coded less. At the weekend I'd spend some of my earnings on a bar lifestyle; I  love meeting new people and seeing old faces.

However, my mum phoned the police and informed them that I was behaving in a strange, mentally disordered way (which I consider to be untrue). I got sectioned over Christmas.

I'm now not allowed to return home, so I'm living back in my university town where I have no motivation for life, no social circles, and no inspiration to code or create. I don't mind so much not being allowed home; I'm pretty old now and can get by on road fine without a bed, but I want to repair the relationship I have with my mum. What's the best way to go about this?

Condense the text into a few key points
<bot>: Mum refuses to talk to me, or let me near the family house due to past drug use. I no longer take drugs. How do I reopen communication?
