You have been through quite the long struggle it seems like. I am glad you have found us here, I hope that you find help and comfort in this group. Your symptoms do sound like they are POTS for the most part to me. But like your doctor said, everyone is different, and that is very true, though everyone here understands each other in many ways, every case of this illness is different and unique to each particular person, so we aren't going to be have the same symptoms necessarily, even though we do have the same illness. I am pretty tired and need to get to bed, so sorry for not posting more-with perhaps more support and help, but I will try and chat with you soon, I am going on vacation with my family tomorrow and get back Sunday night, so hopefully I can talk with you once I get back, I look forward to getting to know you better! I hope you are feeling well, or at least well in spirit! God bless, Mary
