I hope you make a full recovery and hopefully regain any precious memories you may have lost. But someone needs to sit your mother down and tell her to ease off on you. She really should be more understanding, especially where her children are concerned. She may be under stress due to said complication and needed to vent, but there are other ways she could relieve some of that stress. Verbally assaulting you is not one of them.

Tell her you don't remember because you were so wasted. Jk, very sorry OP. Sounds like its been a hard ordeal for you all. Let her know you look forward to enjoying new moments and making new memories with her
