Ask my son to leave.

I had to ask my son to leave over 5 years ago he was addicted stimulants  he was put in a Hostel, was kicked out of a few, his behaviour on drugs is unpredictable,  then ended up sectioned, and was in for 3 years, he had access to his dad's will money and became addicted to crack cocaine  on the ward.
On releas  he was given a flat, I bought his food  all his money had gone,  he was at my door for money all the time and I gave in, I had no support it was relentless,  eventually I got a restrainin  order. He lost his flat was shoplifting, hes been in and out of prison and mental health wards since then. This month he was realised with no accommodation,  he tried to get help , but ended up here i put him up  and tried to get help, To get help with housing you have to prove you are sleeping on the streets,  that's been hard, gave him tent sleeping bag,  got stolen, went out again with warm coat ect told him what to do ie streetlink. He ended up coming back in morning with coat and bag  stolen, I called the police abd hes was in court  this morning and im waiting to hear. He's just no safe on streets, I had peace of mind when he in prison or on a ward,  I confused why hes not housed as he has haemophilia and bi polar. I keep hoping that hitting rock bottom will be what makes him stop. I know he's tired of his addiction. But how can he  get help when he feels like no body cares, I feel so helpless and carnt see any change to his life. I just hope he been given a sentence again.
