Hi jfb, welcome to the board and I am so sorry for all that you've been going through. I remember too well the sleepless nights and finally having to go see a dr. for some help. I know you said that you were in the hospital for a couple of days--were you able to get any sleep medication or anything for depression? The sleep deprivation mode certainly doesn't make it easy to do anything and it wasn't until I started to get some rest that I was able to calmly think and decide what I needed and wanted to do next.
You have been through a lot and it might help you to read through the other threads under this topic and Last Resort. Many of the people on this board are unfortunately wrestling with the issue of infidelity. If nothing else right now, you need to really treat yourself well. Spoil yourself and do things that will bring you joy. I know others will have plenty to add to my suggestions. Take care and come back to this board. Jamie
