Sick of it !

My husband recently found out he had diabetes. & I been stress ! trying to stay calm & strong for him. I hate seeing him sick & cry. But oh man his been a stressing me his been so moody lately & I let it slide. Today ! Was my breaking point. He needs glasses & asked me to go and drop off his old ones and get the new ones I told him it was fine to watch our daughter because it will be a hassle to get her off real quick & leave them then go back & buckle her up. He said it was fine. As I’m leaving his doctor calls about info so I stay to hear and write down things for him. She hangs up & I start to head out & I notice his falling asleep asked him to not fall asleep because I’m leaving our daughter here. He starts to get mad & we get into a big argument & he says some hurtful things. I told him that I was no longer going for him & he calls his mom to go for him because he can’t drive (I’m quite listening)she’s says why cant (me ) go. he told her that I didn’t want to do anything for him anymore & she says she’s going to talk to me that it’s not right ! Like what ! I been going beyond for him & just to tell her that. That really just broke me I know his going through something . I’m really just gunna stay away from him for awhile. Seems like I’m never enough
