What is this feeling....?

Hi everyone, im going through a hard time at the minute, 2 main things recently havig a miscarriage, and just last week my partner got sent to prison for 4 n half years! Ive had a very weird feeling, im needing to grate my teeth, stretch out, my whole body feels agitated and i cant sit still doing nothing, im ok if im on the computer, but just sitting there watching tele i struggle, im really struggling with day to day life as it is and just started anti depressants from yesterday. Im feeling very sick and not able to eat. Obviously im hurting, but is all of this down to that? Really this is a horrible feeling, just being soo aggitated! Any advice welcome and much appreciated xx
