I can relate to only being allowed to work a few hours each week and trying to get that reliably, it can be real tough. I live on a small benefit and try to supplement that with part time work to make enough to live. You need the money to live, but it always seems to little which leads to money stress or too much which leads to work stress (read overwhelmed) and benefits complications.
You're taking some really positive steps and hopefully you can get the help your looking for. You are making good progress and putting things in place to succeed. Look after yourself first, work worries will always be about, you have to make sure your always about
Hoping your feeling better soon.
