Iam really sad, how do i change that?

There are a variety of ways you can make yourself feel better. Indulge in a hobby that you enjoy, or if you used to enjoy it but you haven't done it in awhile (this can possibly* be a sign of depression) try to get yourself to do that thing again.

you can also listen to music, exercise, draw, or paint your feelings.

i think the answer is d.

you would have a std. i hope this .
