I can relate. I've suffered from bipolar disorder & depression my whole life. There are better times, and not so better times. More than a year ago, I was prescribed a new(ish) treatment called Transcranial Magnetic sounding (TMS) which has been FDA approved in the US for some years now. I feel way better. My doc wants me to have another round of treatment soon. I might be one of those who has to have it every couple years. Some patients get full remission of symptoms. It's completely painless too. Way better than the older ECT treatment.
People don't realize how screwy it is to have some sort of invisible disability like anxiety/depression/bipolar/etc. and how miserable one's life can be with it.
I was recently diagnosed with bipolar 2. It's manifested as long periods of depression with shorter periods of hypomania. I believed the hypomanic periods were how people felt normally, but apparently not.
I've usually been treated for depression, since I'd go to the doc when I got seriously depressed. Anti-depressants worked, sort of, but never lasted long.
Now I'm on a mood stabilizer called lamotragine and Abilify, and my mood has definitely stabilized. It's only been 3 months, so will see how it goes. I'm going to ask my doc about TMS, although I suspect it won't be covered by my medical plan. It'd be ideal if I could stay in a hypomanic state, imo, but I suppose there might be downsides.
