I'm so sorry....I don't know anywhere else you could "vent" at this hour. I don't know what to do from here but offer you care and prayers and a gentle hug hon....but others are here too to help. I remember what that was like to feel that way and I'm sorry for that. I know how hard it is.
I know it seems almost a cliche...but try your deep breathing. I know it's hard to concentrate...but with breathing you don't really have to do much. Breathe and a mantra...only if it's "help me God"....it's a prayer.
I'm with you in spirit girl! You know that!
Hugs...d.
