i dont know what to do anymore, weird symptoms help!

About last monday or sunday i developed these symptoms that have occured nonstop since then until now. i went through a small stressful thing but i dont even think about it now i dont know what could be wrong. and i didnt know where to post this itd be really helpful, its ruining my life!

they are-

insomnia
loss of appetite/ two bites and full
empty thoughts
twitches in my feet at night with leg cramping
constant nasuea from the time i wake up till i fall asleep
direahea (slowly going away)
difficulty swallowing(which has subsided)
heart racing almost all the time
~also when im alone i feel like its the worst~

i dont know if this could be like phenumonia, flu, or food poisioning. i've also been reading up on like depression disorders but i doubt that's it or i dont know HELP PLEASE.

Now im no dr but sounds like a bit of depressiom and anxiety. They can cause the shakes, loss of appitite and even physical problems like the diarreah and body aches. What do u mean by empty thoughts? If u dont mind me asking what did u go threw that is stressful?

I have not had a period in almost 6 years now. I have headaches, sever mood swings,always sad or feel depressed. I have a few hotflashes, diahreah all the time, I feel tired all the time have no energy.
