Letting your mind go into "what if's" is something we have all done. If you can find a way to stop yourself (and it may not happen for awhile) and then ask the question "am I responding to fact or fiction" it might help to calm you some.
I'll be honest it took me a long time to be able to do this and sweetie, you are very new to this.
Learning to tie your goat in a new place takes time and patience.
Do you have any physical activities you like to do? I found that doing something physical (minimally a walk) really helped me to clear my head and stop my "second guessing" at least long enough to take a breath.
