2 1/2 years of hell; still not over

I moved out of state in December 2019. Was pretty happy and satisfied with things.
When I moved, things just fell apart, slowly. The number of major life changes I have gone through would blow you away. Example; leaving good job, moving, leaving great friends, having to sell the old house, look for and buy a new house, job hunt, start a new job, laid off a year later, put my dog to sleep, moved 4 times, soon to be ex spouse verbally and emotionally abused me all the decades in the marriage, it escalated a few months ago, I called him on it and he presented me with a divorce "package" he came up with, heaven help me if I challenge it and put forth my own ideas, kicked out of the house and told I could always go to a hotel and now, since the separation, my kids pretty much ghosted me. No communication unless I initiate it (which I'm not doing anymore), no asking how I'm doing in all this, and, my in-laws who said they loved me and considered me a true family member has jettisoned me out of the picture. No communication, no checking in to see how I'm doing...nothing. 30 years of a family relationship gone in a flash.
So, I'm having a hell of a time wondering why I'm worth anything. Why I'm worthy of existing at all. As evidenced by family treatment, I could literally vanish forever and no one would even notice I'm not there.
Thanks for letting me vent guys.
