For me, it was a gradual acceptance of the fact that, for now, this is the 'what is', and not beating myself up about it. It took a period of sort of mantra-ing stuff like "I can't do this right now, it doesn;t mean I'm lazy, or that something awful will happen because I can't do this right now, it just means that for now, I cant do it." I had to repeat that every time that particualr kind of anxiousness started up. You have to kind of retrain your expectations.
I'm really glad that SSRI's worked for you, as they have for some lucky others. But when you recommend them to others, you need to be aware that what's good for you could be poisonous and damaging to someone else before making a blanket-statement recommendation like this.
No matter how harmless and beneficial many in the medical community express antidepressants to be, they're psychotropic drugs that fiddle with, and alter, brain function, and as such should be approached with respect, great care, and extreme caution.
