So how long does this "acceptance" sh*t take then?

Hmmm.......so 4 months into my 'diagnosed' state (48yo), and I'm not feeling a whole heap of acceptance. I am still feeling quite bitter and resentful. Everything I see around me in life and at work seems to have been, and continues to be, designed with a slightly different species in mind.

I have started reading this forum more often, even though I'm scared of keep seeing my reflection in these threads, and am following some overtly divergent contributors on Facebook. I was skeptical that at my age, with my history, that I could somehow find 'inner peace' (I mean, really - what the hell is that even supposed to mean?), but at the moment I'm heading in the opposite direction. Those long-cherished hopes of finding the right therapy, the right antidepressant to 'sort me out' seem absurd. 

I recall seeing a quite old entry on here where a user refers to feeling much better about the state of things 4 years in. FOUR YEARS? (yes, I am shouting). I don't think I can maintain even the current crumbling facade for another 3+ years. Especially now I recognize the effort I am putting in, and the energy this costs me.
