My husband is a f***ing nightmare!!!!

I just need to vent some. My husband is a nightmare. He has a lot of on and off health problems. So he ended up going to emergency room last night for severe pain. He complains sooooo much. Wants to refuse certain treatments like getting his blood drawn or getting an iv because he hates needles. He bitches about every single thing known to man kind. Today he is still in pain even after taking the meds that were prescribed. Still bitching about everything possible. Refuses to go back to the emergency room because he is NOT getting his blood drawn AGAIN. I am at my whits end with this man and just ready to walk away. I hate to be like that but he is just too much for me and gets shitty with me and yells at me over everything, related to his health issues or not. I schedule him a doctors appointment and ask him if that day and time is okay and he says yes, but then when it’s time for the appointment refuses to go and tells me he’s not seeing a dr and blah blah blah. I’m so over it all. I just needed a rant. And maybe some advice or encouragement because he is taking a serious toll on me!!!!
