I have the same problem as you about the crying especially at certain moments. I may have mentioned the book There's a Spiritual Solution to Every Problem before, but reading something like this might help you. I know when I feel the tears coming on, I picture my pain becoming peace. And many times I truly can feel the peace inside me replace the sadness.
Have you tried St John's Wort? Some good recent research has shown it's as good as the prespricption stuff without the side effects.
You are in a good position in your sitch since your H is still living with you. Mine is gone, though we do date and have regular sex, I would rather him be here and doing this stuff.
