Hi, When I m Laying down trying to fall asleep or taking a nap mostly my legs but sometimes my arms Twitch a little. I only sometimes, I feel like I m falling or hovering up, but that has only happened 1 time. I have been believed to have High Fucioning Autism all my life, I am 10-but I ve only known this for almost 2 years. I have been swimming a lot, almost everyday for 3 or 4 days, but I also have stress, and I am scared of somethings I do, or places I go. Please help, I m scared!
