I like you, also became unemployed for years. Whenever I tried to get a job, I was just so socially awkward on Adderall, I couldn't get hired. I think I was too stiff, too robotic. No one wants to hire anyone like that. I also took 60mgs for years.
On the last few years I was on it, I wasn't even doing anything. So it's kind of like, "What are you using it for then? whats the point?" I totally relate to that. But you are so addicted, and you cant get out of bed without it, so you might as well. It's just a cycle that continues and an addiction that is so hard to break. It almost feels like you cant survive without it. I totally get it, and I was there.
BUT, I was wrong. I could survive without it. In order to go out there and socialize with people again, and get a job, I needed to quit. Staying on the Adderall is not going to help you move forward, you are going to remain stuck. But you will only remain stuck for a good 10 months or so. It's really not that long. On Adderall you can end up staying like this, unproductive for years.
My advice is to start tapering off of it now. I did a successful taper. 1 week I went down to 20mgs, the next week maybe 10, and I slowly decreased just like that, and by the 3rd week or so, I quit completely. I would just prepare to do a whole lot of nothing, but as you have described...it's already what you have been doing, so this is the PERFECT time to quit. I don't even think Rehab is necessary. I would save my money and quit on my own, you can do it.
