Does being really sad or depressed actually cause physical symptoms?

I mean beside crying I’m not big on that so I tend to not let myself cry but anytime I hold emotions like that back I always get like these headaches especially if a situation is making me very depressed and stressed as well usually dealing with woman. I read online that being depressed does cause physical symptoms like headache, muscle tension etc I’m some cases. It’s really crazy, have you ever experienced this?
