Oh
. Well if you end up feeling really desperate you can always go to the ER, and they'll have to admit you.
In the meantime, until your new medicine has some time to kick in, you should do something nice for yourself that you enjoy. Such as taking a walk or a drive, going to your favorite place to eat, taking a nice hot bath, watching a movie, or playing with pets if you have any, etc. Sometimes it's the small things in life that make it worth living for me when everything feels hopeless. Also, anything that keeps your mind occupied can be a good thing.
