I too have moments when i feel like i am just going to burst out into tears, which i know will only make things worse. But, it is hard to have that self control.
Trust is a huge issue...i struggle with this one myself. I sometimes think, if my H came back to me, what would it be like? Would i constantly have a gnawing feeling in the pit of my stomach? Will i freak out if i can't find him? What kind of life is that? Right now, though, its not really an option since H doesn't appear to be coming back any time soon...if at all.
Sorry that you had a tough day on Saturday...i hope the rest of your weekend was better. What i've learned is that even when we think we can't handle anymore, we somehow get that "second wind" and pick ourselves back up. At least that is what happens with me.
