Feeling hopeless

Hello everyone. I recently got into a car wreck and thought I found my legal answer with 7oh. Now a month later, I am experiencing withdrawal. To top it off I have been in recovery for the last year and living in a sober house. They found out I was on Kratom and tested me and now they’re kicked me out to the streets. I get paid biweekly and it being the beginning of the month, funds are non existent. I am terrified of being out on the streets going thru this and being in pain as well. How long does this detox take? My back is pretty messed up still from the accident and makes it hard to walk. Thanks in advance for any advice
