Hi there,
I use to live close to where you are in PA, but that is not the reason of my reply, it sounds to me you may be bipolar, but there are other things possible, this was just the first thing that came to mind, before my diagnosis, I went through something that sounds just like what you have mentioned here.
Have you ever been given any diagnosis? Do you use amphtemines? Have you possibly been mis-diagnosed with ADD? Bipolar and ADD over the years have been misdiagnosed by some pdocs because certain behavioural patterns are similar, but if you are bipolar and given Ritalin, Cylert, or any stimulants due to the fact a pdoc diagnosed as ADD and not the proper DX, this can wreak havoc, just exacberating the racing thoughts.
You may want to take this up with your pdoc, or seek a new one and have an evaluation, there can be a possiblity that there will be a need to change meds. I found when put on mood stabilizers and additional meds, the too much thinking or racing thoughts subsided, and it also allowed me to sleep, otherwise I would go through each day on only 2 hours sleep per day, in time a person will "burn out" and that is a horrible experience. This is just a few of my personal thoughts on your post, the best thing is to consult with a pdoc.
I'm not saying the above is the only thing(s) that are possible but may be something to investigate.
I do know when I lived near your section in PA, I did work on a volunteer basis at one of the schools there in Chester County and there had been a lot of children misdiagnosed as having ADD/ADHD, put on Ritalin and they only became more hyper, and were NOT ADD/ADHD, that is why it is important to seek out a pdoc, even ask your primary care physician for a referral if you are able to. You do not have to live like this, there is help
