I just want someone to relate to

Im genuinely so exhausted. Both mentally and physically with whats been happening with my body. Idk if its Pots or even related to Dysautonomia but it lines up pretty well. Im currently at work and just kind of, blacked out? For like a second. A literal second. But my body, I feel EXHAUSTED. And weak? Like, weak in the head…? It doesnt help that Im so bad at explaining things. I just want to lay down and sleep. Granted, I did have to use the bathroom, usually bowel movements cause a vasovagal response but a couple weeks ago it got TREMENDOUSLY worse. So I probably blacked out form having to use the bathroom, but ohhhhh my gooooosssshhhh Im just so agitated at this happening and not knowing what it is. Used to think it was my anxiety but I started taking an anxiety medication a few months ago and its helped me soooo much. I dont think its my anxiety anymore I think its just my body not being able to handle certain things. Like SITTING DOWN?!?!? Uuuugghhhhhhh and it sucks because I dont know whats going on and I dont know who to talk to about it that I can relate to BECAUSE I DONT KNOW WHAT IT IS. I went to the doctor (who wasnt my primary because shes out for a little bit) and he just said get some compression socks which yes I think is a good idea but also he didnt let me get more than three words out. Im exhausted Im a bit scared and feel like im straight up dying sometimes. Theres a long list of things I deal with and Im ready to find the answer of what it is and the solution of how to live and/or fix it.
