Dear Amore:
There's no easy or single answer. You'll find many others, myself included, who were in denial episodically. I wish I knew what to say that would be immediately relieving and uplifting . . . I don't. That's the reality it seems for a while; how long is largely up to you.
If that sounds harsh I say it from experience and with the deepest empathy I am capable of, for the place you are at was my zip code too. In the end I listened to my therapist, psychiatrist, and endo. Life moved on and after crying for every night for over a year I slowly clawed out of that place. The good news was as soon as I started it got better very quickly, and I noticed that when I felt guilty and a failure that it had little to do with life that was coming at me as a woman - a life of being me, a woman thank goodness.
During that period I narrowed my options down to taking one little step, emphasis on little, every day. Occasionally I'd back slide, but in the main there was eventually a path I took to accepting that my life, as it was recreating itself was a sweet, beautiful thing . . . to be lived with peace and joy. All from taking one step at a time (and recognizing that the past was just that and it would never be a satisfactory substitute for the future).
You are a beautiful person with a mysterious and wonderful gift; it just isn't easy to accept that gift at times early on or ongoingly for that matter - that is until you can claim who you are. And in closing, it will happen for you - just one little step at time.
Take care and please stay in touch,
Rachel
