How wonderful that you have accomplished such great things; first, the education of your children, then the beating of cancer, third, you know "the truth about the truth."You are obviously a strong person.
I know the feeling of not having friends. In the congregation we had instant friends and lots of them. In fact, sometimes I felt overwhelmed because I knew so many people and felt that I couldn't properly keep up with them all to the extent I should. Now, none of them speak to me or my husband, because we are "dangerous." Yes, my husband is "out"with me, but he doesn't want any friends...well actually he does, but is afraid of being hurt. At any rate, it equals lonliness for me. I feel that I can't leave him at home and go places or he'll be upset.
My advice to you is get a part time job. That way you could get rest in between the times you had to work. It would also get you out of the house and talking to people again.
The second thing is that you need is to compromise with hubby. At least one weekend a month, go do something together as a couple instead of going to the meetings. Maybe he would relax and feel that he could be a bit more open with you about his doubts.
Wishing you the best. I know that we are all just connected by computer but I hope you can see that we care about you.
