Anyone end up stopping cold turkey?

I think last night was the worst night of my life. I most definitely have had nursing aversion/agitation for about 8 weeks. I'm 14 weeks pg. I feel like I am going insane. My son has been ill with chest & ear infection and had s&d so I have been feeding him throughout the day and throughout the night. Last night I just wanted to scream through every feed. My OH just kept saing that its my fault for feeding him fur this long, he's only 15 months?? I cant gradually wean him as he wants boob all the time. When I say know at night he will scream until we either takes him down stairs and calm him down or I just give in and lie there crying while I feed him. I just don't understand what to do. My love for him is so strong and to stop feeding him just feels like I'm punishing him. I totally stuck!
