Is it wrong?

So over the past couple years I’ve had a rocky relationship with my mom, she used to be an alcoholic and I felt like I lost my sense of closeness with her due to going through that.

I just started a new part time job at Menard’s in addition with my current work from home job. I work about 25-30 hours at Menard’s, and spend my down time with my parents. I recently found out that my mom has breast cancer, the doctors said that it’s in a really early stage and shouldn’t be anything to worry about- they’ll schedule a MRI and tests, and a surgery within a month or so. Of course I’ll there for her and my dad for all the tests, surgery, radiation, etc and try to stay as positive as I can for her and help out with everything at home.

But I wonder, would it be wrong of me to pickup extra shifts at my 2nd job to keep my mind off all this? I feel so awful for thinking I need to work more and not be there for her all the time, but I’m so stressed and emotional about this that I feel like I’ll burst into tears every time I see her.
