Tiredly Tireless

This Borderline crap is for the birds.
I'm fed up with feeling like I'm the only one feeling these things, like I'm the only one who over-reacts, the only one struggling. I go to group outpatient therapy from nine to four every day, Monday-Friday, and, honestly, being surrounded by a bunch of military men all the time, hearing them make the jokes I used to think were funny, talking the crap I used to get heated over and throw a put down in their face for... It's like I'm constantly being reminded of what I no longer am.
I know I have made progress, as I've gone from that unstable, constantly-changing, fluctuating sense of "self" that depended on who I was around to this emptiness, this total lack of self all together... I know I've overcome some of my issues because I recognize the all-or-nothing thinking, and, sometimes, I can even control it. Honestly, I usually think I do a pretty good job lately in controlling at least the majority of emotional reactions... But judging from other peoples' responses to them, I could definitely be wrong.
I feel like a lost cause. The numbness is becoming the norm, and I'm not used to being numb or calm, I'm used to passionate, overwhelming emotions. I don't know how to deal with a total emotional void.
Tuesday or Wednesday, I fell apart for the first time in a while- the life-changing, I-can't-do-anything-right, I'll-leave-you-alone, I'm-hopeless sort of falling apart. I spent nearly two hours sitting on the bathroom floor of the clinic I go to outpatient treatment at, sobbing, afraid to come out, afraid of what would happen if all the guys saw me that weak... The next day the subject of sexual coercion came up in group and I had to walk out just to deal with the tears that came at the mention of details. I am so tired of being this fragile person. I miss being tough and strong and unbreakable.
My heart pretty much breaks on a daily basis now. I guess, at least for now, that's what I've traded the worst of my temper tantrums and over-reactions for. I'm sure it gets better... I'm just really hoping that part comes soon right about now.
