In a funk

So recently my two Best friends and I had a fall out... I found out they were talking about me and also playing both sides of the fence with someone I don’t care for. The same night my SO and I got into a huge fight where we just finally made up yesterday. Anyway all of these pushed me into a pretty deep depression I don’t think I got out of bed for 3 days straight barely ate.. I’m starting to feel a bit better but how do you guys handle things when they get tough?
