It's been 5 years. The first year was really tough, but with a lot of hard work and support, I was mostly healed. In spite of a really awful divorce, which is still in court, although the marriage has been dissolved.
"Mostly". After trauma like this, I think you need to understand that healing includes scars, and sometimes the scars itch.
After year 1, I was more comfortable with change in my life, I was (for me) optimistic about the future, I was dealing with reality, I was off most of the emergency drugs, and weaning off the rest.
I had setbacks (the roller coaster) during holidays, or times I had to deal with court, or with now-X about kids or the granddaughter. That was expected.
What surprises me the most is that my body or subconscious remembers the significant antiversaries even if I don't.
The first couple of years, I got caught up in anticipating them. D-Day#1, D-Day#2, X's birthday, wedding anniversary. I got more and more nervous leading up to them. When they actually arrived, I was pretty ok with them, but the anticipation was pretty bad.
I have gotten to the point where I can look at the calendar and see the date coming up, and I'm mostly "meh". A couple times, I even forgot it was coming.
But my body didn't. There were different symptoms, and they puzzled me, until I figured out the date. Anxiety, nervousness, nightmares, nervous energy, sleep issues, a sense of foreboding, that kind of stuff.
Last weekend was the 5th antiversary of D-Day#2. I actually forgot about it until yesterday. I think one of the reasons I forgot was that I spent it with My Lady (that's what I call my LDR GF when I'm on SI). We celebrated her birthday, which happens to be a couple days earlier, and we celebrated in grand style, with vacation days off work, a brief side trip to a really nice tourist destination, and cake. And whatnot.
But I did have the nervous energy, and sleep problems, including a nightmare. I wrote it off as not wanting to leave her, which is so true. But I think it was also related to the whole D-Day thing.
I'm all better now. These things pass quickly nowadays.
But when you're looking at the healing timeline, remember that the new, healed you is not going to be exactly the old you. Some of the changes will be better, but some of the changes will be scar tissue.
