Working

So about 4 weeks ago I started a new job. I studied and got my home health care license and started work. I love the work and it's only 12 hour a week. But ever since I started my anxiety has like tripled! Mostly because I am a worrier but it is also hard because I lives are already so busy and we can't afford child care so I have to work nights. I was also under the impression that I would have a set schedule but that does not seem to be the case. So with all of this change Michael has been in a really bad mood and never wants me to leave his sight. He is not eating solid food and is not sleeping well. He does not understand. Kaylee understands and really does not complain about it.
Each week I feel more and more guilty and stressed. I am holding my breath waiting for Michael to understand. Today I spent almost two hours going over are expenses and bills trying to figure out where we could cut things that we don't need. I really think that Ken and I live within our means and the only things that we should cut are maybe the trips and camping we do with the kids. But then I feel guilty  because Kaylee  looks forward to all the small little trips we go on . Is it wrong of me to want to stay Home and still work on stuff with Michael? Am I giving in to him if I quit?
I found out today that next week I am going to need a small out patient procedure on the 12th and I am stressing about that because they don't want to to lift or bend for a few days. I really wish I had parents and or that grandma was 15 years younger! I listen to friends and other people complain about their parents and to honest I am jealous. I wish that I had a mom or a dad to talk to about life issues or to advice from.
Anyways enough complaining I know being an adult is hard.
