I've had ADD (Or ADHD, I keep reading psychology journals that flip flop on whether they're one and the same or not) my entire life and it has always been a major detriment to everything I've tried to do. The only time I was ever a straight A student was my last two years of high school because I finally was able to get on adderall and it worked, albeit it took my appetite away which caused my doctor at the time to take me off of it.
I was told it would get better as I became an adult but it hasn't. If anything, it's gotten worse. Even things I enjoy have become a struggle to maintain attention on. Most days I remain so unfocused and switch from one topic to another or one point of interest to another so rapidly I feel as if I'm in some sort of permanent fugue state. For the last three years it's even started to affect my ability to hold down a job and to complete my engineering courses. I did so poorly last quarter that I've essentially dropped out at this point because I simply cannot control this on my own. I already lost two jobs because I keep making stupid amateur hour mistakes that I know better than to make but my attention keeps lapsing constantly.
I really, really want to get back to using what works, but I don't have medical insurance at the moment (Thanks USA healthcare, or lack thereof) and thanks to a series of financial emergencies my fiancees family caused her and my dog getting herself injured, I don't really have enough to go get diagnosed again AND pay for medication out of pocket.
Until such a time, I've been looking for more holistic methods of controlling or lessening the symptoms of ADD/ADHD but nothing I've found online has really worked. Caffeine works some of the time but usually within a week of regular drinking it loses all effectiveness and I need to drink more and more to get anything out of it, which is unacceptable since it also messes with my sleep schedule. Meditation is just straight up impossible for me. I've been trying for ten years and my mind is impossible to quiet long enough to make it habit.
I just don't really know what to do at this point. If this continues, I'll probably lose my current job before I even qualify for it's medical benefits, and then I'll get stuck in a cycle of "I require medication to do the job I can't do because I don't have the medication to allow me to focus enough to do my job".
Would anyone here know of anything that be cheap or DIY that would work for an extreme case like myself?
