Postural Orthostatic Tachacardiya and Ehlers Danlos Syndrome

I hate these disabilities...my parents don't believe that they make me hurt so much and make doing simple things so hard. They hate that I use a cane and body braces but it's hard to go without them. I wish I had forearm crutches so much but they tell me I don't need them and I'm overreacting. I have to walk so much at school so I come home extremely drained and in a lot of pain. My joints feel like I'm gonna fall apart like legos and my head feels like a weight was put on top of it. I can barely keep my eyes open at the end of the day. I have to hide the fact I'm in so much pain because if I spoke up at all, I would be shunned and laughed at. I had a doctor who listened to me but I barely get to see her. She tested me for Rheumatoid Arthritis but nothing came up in my blood tests and so my mom just assumed I was fine. I tried to tell her that it wouldn't show up on blood tests. The day I get crutches and a wheelchair for long distances is the day I will finally be comfortable and happy. That day isn't going to come while I'm under the same roof as my parents.
