I am thinking of doing the same thing now. I am not happy at all on disability. Miserable. I want to have a job tomorrow. It would have to start off part time, both for adjusting to a schedule, and to not give up my disability until I am ready to do this.
I have been looking for a job related to my previous field of work, but I am overqualified for all that I have been applying for. So no job at Geek Squad. So I have been investigating tech schools in order to become certified in areas related to the jobs that I am interested in. I may be twenty yrears out of date, but a certificate(s) would prove that I am aware of current technologies. So I think this is one approach to consider. I will not to go for the degree, but instead get the certificate.
For the time being, I am thinking of volunteering on a regular schredule. This can help ne be more prepared. If I really need the money, I may have to get some part time job in retail. I will not work for McDonalds! I will never let my daughter see me in one of those uniforms with a cap on my head!
So I think the OP should consider a certification at a public tech school. A part time job can help with school expenses, perhaps in retail. At the very least, volunteer somewhere on a regukar basis.
