If you're like me in this manner it's rather like returning to the scene of a horrible accident. I'm not sure what kind of encouragement I can offer but you did say 'let go' and not 'escorted off the premises in handcuffs' so that can be something to help power you up maybe. There IS also the possibility that they want you to come in so they can talk to you about giving you your position back. I don't know as much but if you enjoyed your time there and they cut you loose due to being overstaffed there could be a door that was just temporarily closed. But either way I do relate with having my world yanked out from under me. Just try and keep your thoughts in a positive frame. Hope you get through it well
