Dear Patricia:
You are welcome. Being as anxious as you are and have been for a long time, of course you want to feel better. As long as it is helpful for you to post, keep doing so here. To get a long term relief from your anxiety, in the context of this relationship and otherwise, you will need to… well, relax.
To relax means to take more and more breaks from your overthinking brain, in such ways as aerobic exercise, yoga, meditation and such. Quality psychotherapy will be very helpful to you.
There is work for you to do. Thinking this further while distressed will not work for you. This anxiety, this distress does not allow good thinking.
So relax first, then think, maybe re-read and evaluate the replies you already received and may still receive.
