So sorry to hear you are still dealing with this! Maybe once you cease breastfeeding things can balance out. Maybe not, it can be a scary thought! I heard a few girls say symptoms returned after stopping breastfeeding but I will do it out of courage and not of fear; because I won't let fear rule my life anymore... I felt amazing the last year and that has encouraged me and I know it is possible to feel normal again, and I am 100% sure that all my symptoms were hormone related and that it can be manageable with the right help.
I wish you all the best! Keep your Head up you are doing a great job, dealing with symptoms and being a mom is one hard thing to do.
