Dear Depressedgirl, I hope by now you are feeling a little better. Unfortunately, we go through these spells that seem like they are never going to end. But eventually, we see a little light shine through. I think you really need to get some rest. You need to set aside agruing with fiancee and get some sleep. I hope he loves you enough to help you get some rest and let problems go for right until you can cope with them better. I know without sleep I spiral all over the place. Hope you feel better soon.
