Bad mom

I have a UTI and vaginosis. I’m on 2 different antibiotics. I’m in a lot of pain. My son and I are both coming down with colds. Basically I’m feeling really awful. I don’t want to be near my son at all. He’s testing boundaries and he knows I’m not up to my usual level of parenting so he’s been awful. He won’t stop and I’m exhausted. He is testing limits. I just don’t want to deal with him right now and I know I shouldn’t feel this way because he’s my child. I’m a single mom so it’s just me and I normally am fine but I think I’m at my limit. He’s currently tearing my room apart. A couple family members will be taking him for a bit so I can get some rest. I’m just so exhausted and frustrated and I feel like such a bad mom.
