Insomnia! help! please?

i am slightly high (not drug related high, as in a high mood) and totally cannot sleep! i don't know what to do! i am also suffering severe paranoia, i cant leave my living room to even go to my kitchen atm as i am petrified, should i tell my dr of this??? i feel very restless, i have been diagnosed with depression. i don't think this has anything to do with depression, im not on any meds........i just cannot sleep.....and i feel quite agitated and i dont know...its hard i just dont know...any ideas!!
