Anxiety over leaving DD

[girlmama22]

I start a new job tomorrow after being a SAHM for the past almost 3 years, it's only part time and MIL and DM will be splitting the care of DD between them but I feel so so anxious about leaving her.
I've left her before and it's never been an issue, she absolutely loves spending time with DM and MIL so I know she'll have a ball but I feel like it's different because I'll be at work and unable to just go to her if she needs me or anything happens, I suppose I feel a bit out of control of the situation.
How do I deal with the anxiety over this? I feel sick and have cried multiple times today over it. I've spoken to DH about how I feel and he's been great trying to reassure me etc but he doesn't fully understand why I feel the way I do.

The joy when you get home after work is indescribable! Joy from you and joy from the little one.
I was dreading leaving my son to go back to work full time but I took a month to get him settled into nursery and used to it before I went back,
I knew he was happy and the money in the bank helped give him a better life.
I went back full time and a year later our routine is down pat. The cuddles in the evenings are great and weekends feel more special,
Work is good for me and good for him too.
