Help!! Rant!!

So my husband has diabetes. He was diagnosed three years ago. Today he felt bad because his sugar was high. It was in the 600’s. He hasn’t been talking his insulin and checking his blood sugar. So he felt sluggish and tired all day. So he got off from today to stay at home . So our baby stayed at home with him. He didn’t take her to daycare because he felt too bad. So I asked what did you do all day he said slept. He said he barely had energy to go to the bathroom let alone take care out the baby at home. But he said all my baby did was stayed in her swing most of the day and slept. She doesn’t do that with me or her grandparents because we interact with her all day. But our baby is 5 months old. So she is learning how to pull herself up to sit up by herself. So when I got home she wasn’t buckled up in her sit. My husband just makes me so nervous… my anxiety has gotten worse since having my baby. I tried to tell him to go the doctor or the hospital but he said no he’ll just wait until it gets worse to do something about it. I’m very tired of it tbh…
