Unit Closed, feeling lost.

The unit I worked on has recently closed permanently

I worked there for a short time but enjoyed working there. I have been transferred to a new job within another unit which I start soon.

Im feeling really lost though and I am really struggling, to cope with the thoughts that I won't be working in that unit, won't be working with the resident's or the staff. I enjoyed my job there and we were a very close unit and staff were very supportive of each other. I feel like I've lost my whole Identity. I don't know how to cope. I didn't think I would feel like this as ive had a while to come to terms with the closure of the unit. Ive been sitting thinking about residents and the staff constantly. I'm afraid of what the future will hold. I feel like I've got nothing to look forward to now, I looked forward to my shifts, as I had fun at work. Ive tried to speak to my friends and family and they said to focus on my new job and forget about my old one. How can I forget about a place that is so important to me, about the residents and the staff. I know I will see my work colleagues regularly but its not the same. I don't know what to do, my head is so blurry and my heart hurts. I am exicted for my new job and new adventures but I just keep replaying fun times I've had at work.
