Hi, im a 24 yr old girl.. i hv been going through very bad headaches for the past 9 year's now.. but thats another thing.. from a few years almost about 5 year's im dealing wid insomnia i tried many things but it doesn't go away,i only have thick sleep when im too sick, otherwise i don't even remember whats a normal good sleep is,im not able to sleep until it's sunrise,no idea why.. i hv social anxiety, whenever im in a crowded place i get anxious i try my best to be cool but doesn't help,i overthink too much,im sad all the time, I don't feel happy in doing anything, I don't go out or talk to people it's really hard for me to do.. extremely hard nobody at home understands any of this,j n i when i talked abt dis wid multiple neurologist's dey just suggest some medicine which makes me dizzy and sleepy all the time so i don't function either way.. plz tell me what can i do with all of this .. thank you
