How to rid myself of Anxiety/guilt husband after year hiatus, starting new job?

So several months back I was in freak out mode because my husband was drinking a lot, had been fired from previous job of 10 years.. he wasn’t even looking for a job for about a year and just totally depressed... fast forward.. here we are.. he applied for a couple jobs and magically after a week secured a dream job.. funny how that works sometimes isn’t it?... he’s been taking care of the baby.. I’ve been working on my own business providing all of the income.. very untraditional roles.. well here we are now.. he started his new job today.. I’m at home with the baby and working (which is tough, she’ll be set to go to daycare in a week or so).. I’m having SO much anxiety today.. I miss him being here, and now looking back love that he was taking care of the baby while I worked..selfish I know.. but I can’t help the way I feel. I also feel guilt that he’s getting up so early to go to work.. while I (for once in my life, as this work from home thing is a recent development, another story) am able to sleep in until 9am.. roll out of bed and work in my PJs.. just anxiety all around.. anxiety also the little one will soon be going to daycare... I can’t shake the feelings and it’s really throwing me off today.. how do I ease this? Anyone been in similar boat? Did it get easier/better?
