need some encouragement...

doctor had me on leave for 3 months due to hypermesis and currently 33 weeks 4 days. well I went to my apt and he said he is sending me back to work for 3-4 weeks and thinking about going to work has been giving me anxiety and has me feeling sad. I have to go back and deal with people. I travel so it's new coworkers new place new location.... it's to the point where I can't even sleep.. I sleep for about an hour. I know the weeks will fly by but I just need some people to tell me I got this or something .... maybe I'm just exaggerating but I just feel really scared ☹ after that he said by 37/38 weeks he will put me on leave again ...
