After I went through my divorce, I found myself questioning everything about my life. Others are born to mid-life crises, I had mine thrust upon me.
What helped me a great deal was individual therapy. It was amazingly helpful to have an objective, outside person tell me whether or not some idea or opinion I held about myself was, in fact, true. It really helped me untangle a lot of swirling emotions and ideas that I endured months after the divorce was final.
I hope you find a path forward that works for you! Hugs, HG
