Hi Hbb,
I'm so sorry for your pain, and I understand how you are feeling. It is such a defeating feeling when you are feeling great and suddenly BAM! you are stuck in a rut. This is normal, and you will pull out of it. It's the process of grieving; everyone grieves over something that has ended--regardless of whether the situation was good or bad--it can be a loss of a dream, a realization that things didn't turn out how you expected--and these feelings take time to process. So let yourself feel sad, cry, or rant. Then pick up and move forward. It is hard...but it will get better. Hugs to you...
