Help don't know what to do 🤦🏻‍♀️

Long story short : my husbands has leukemia. He got diagnosed back in April . I been the one who been taking him to his appointments everyday ... today he got a headache while waiting to call him in the clinic to get chemo ... he couldn't handle it any more so I decided to go ask around if he can get some for a headache they let me know they didn't have anything... so he got mad and started crying and he said let's go once we got home he threw up in the driveway ... I told his mom I felt that she was mad about leaving his appointment... he now crying that he has let down everybody by leaving .

I don't get what am I supposed to do ! If don't listen to him he get mad and tell so many things . But I understand he says thing cause of what's he is going thru . But come on now I have a 1year old I don't get to wake up to ... because I'm supposed to take him to his appointments and his mom not once has went to his appointments by herself ....

I'm stressed and tired . Iknow crying isn't going to help anything
