Hi Heather,
Welcome to ANA, you're with friends who are willing to listen, perhaps dole out some advice, but more importantly, you are talking to people who know EXACTLY what you are experiencing and going through. I had my AN removed 11 months ago, there are days when I regret having it done because my life hasn't returned to normal, and I am afraid this just might be the new normal for me, although my doctor keeps telling me I have more recovery left. I'm not going to give you a litany of my symptoms, but I have some of those you have mentioned. What might help you with memory is Omega 3 Oil. You can get it naturally by eating fish, I find a meal of salmon helps. I have also had a lot of success with Omega 3 through Flaxseed Oil. I would suggest going to the Vitamin Shop and speaking with a sales person that knows their stuff. Quality sleep also seems to help, and as crazy as this sounds, exercise your brain. I do by reading a lot. I hope this helps, please don't be discouraged, take one day at a time, and be thankful for all we have.
God Bless.
