I am divorced, have family support, but I understand how you feel, it has just being the last few days that I don't feel like crying when someone asks me, how are you?
I call my whole experience a tsunami, I find that to get back to "normality" I do physical things. Somehow it helps me feel better, I even boughht a painter gadget and painted he walls of my garage, . It may sound simple minded, but it has helped me feel better and take my mind off the cancer black cloud that I was on.
I went to one support group event, but I came out more depressed hearing nothing but problems.
I am glad for you that you have a great husband, right now I wish I had one, but my ex would not be a loyal trooper,
Anyway, I hope your pain goes away, I did not have that, mine was more emotional, and feeling lonely even if my family has been supportive, but at the end if the day it is different than having a partner in life.
