I feel like a failure to my mom. My mom is still trying to get me to do housekeeping at the nursing home because the aids are all having to pitch in there too. And I know she's upset with me for not wanting to do it. It isn't that I'm not wanting to. It's that I refuse to deal with the unprofessionalism of the building. I am sorry that I'm not doing it because I know they need someone but I'm not going to sit around and be treated like I don't matter. I see how my mom is treated and I won't do it. I have 2 kids and a husband. It seems like no one else is capable to watch both kids together except for me. So how the hell am I going to leave them alone for 8+ hours even if it's for 3 days a week? I can't do it. I miss them in the hour I go and clean at the other job 2 times a week. I worry that no one can handle it. I shouldn't feel this way but I do. It may be separation anxiety but the feeling is still there and I don't know what to do.
