“Is this just all in my head or growing pains or is it something more?”

I have aching pains in my joints specifically my fingers, wrists, knees, shoulders, and hips. I have stabbing pain or numbness in my hands sometimes it feels like I'm wearing a glove. I have a constant mild headache. I have chest pain sometimes it feels like my chest is going to just collapse it feels like there is pressure on it. My arms and hands and legs sometimes feel very weak and it takes a lot of effort to move them. My joints sometimes don't feel like they are quite sitting right in their sockets I can move them when that happens but it's quite painful. I often feel faint when I stand up or stand for a period of time, my vision will go out ill get dizzy, and sometimes start to fall. my skin on my hands sometimes tears for no reason like I will get cuts on my hands when they aren't dry just by moving them. I have hypermobility in a few joints I have a Beighton Score of 6. My skin is pale and the veins around my eyes are very visible I can also see all the joints in my hands clearly under the skin. Is this all normal or just in my head/growing pains? It's been getting worse and worse for around a year no one takes me seriously because I push through it all and pretend I'm fine. I've half convinced myself that this is normal but I'm not sure.
