Money/work problems

I am trying to stay optimistic but it seems like small things stress me out so bad to where I want to cry. My work who wasn't planning to pay me maternity leave at first has agreed to pay me 4 weeks maternity leave as long as I am always available. I'm a manager of a locally owned tanning salon and I have to be able to answer all calls while I'm out. I know that seems so small but I just wanted a little bit of peace and time to not worry about work just focus on my new baby and family. This really just makes me want to cry, maybe I'm overreacting. I can't afford to not get maternity pay tho because SO got laid off 3 weeks ago so I'm stuck paying all the bills. My hormones are going crazy, I need a break.
