Newly single help please?

My boyfriend and I broke up yesterday and im so depressed. It wass mutual thing but I miss knowing he's there and that I can see him whenever I want and hug him and cuddle. I just feel like my heart lost a piece. I want to go out and do something to take my mind off of it but Whenever I even start to get dressed my heart hurts and tells me to go back to bed and be depressed.  Idk what to do
