While I was not officially diagnosed until last year (I am 50) and was never properly treated for all of those years, I had gained some insight in my latter years and knew that my issue was more than just depression. Anyway, I had a "lull" that actually lasted a few years. I was still cycling but didn't wreak too much havoc during the hypos and the lows were not that severe or debilitating....and I had convinced myself that I had 'outgrown' my issues with age. Ummm, yeah.....about that...about a year and a half ago all hell broke loose and I crashed my world with guns blazing. Wreaked havoc impressively. Ended up IP three times in just a few months battling extreme depression.
To wrap up this long story. Finally got dx'd, started a med regimen (never found the right combo), lost my insurance (and therefore all tx and med) and am now waiting on insurance to get back into tx.
And the sobering realization that I didn't and won't outgrow it. I need to become more self-aware, more vigilant in my self-care, get in tx and have a tx team and support group....just be smarter about my MI and taking care of myself. . . for a life time.
