It is genetic in my case. And since it comes from both sides of the family (though both my parents were lucky to escape it, and I'm assuming it is a recessive gene) my brother and sister have it too. Fun times.
I'll likely be on medication my whole life, as I think I went into "partial remission" after getting the new TMS treatment rather than total remission. (Some tms patients do.) I'm having it done again in a couple months. But suffice to say that after having the TMS treatment, the medicine actually works. It was doing a half-assed job before, and in my case--not saying you're wrong to try to treat your anxiety in other ways--other, non-medicinal treatments are ineffective, since we're talking about full-blown bipolar disorder here.
I do hope you get better. People don't realize how crippling mental problems like anxiety, depression, bipolar, etc are.
I agree bipolar disorder, schizophrenia etc are almost always genetic disorders. Probably in my case as well, but who knows.
Thank you I hope you keep getting better as well.
