Me and my girlfriend just broke up, any advice to make me feel better?

It has been my longest relationship and i know its kinda sad to be upset about it this much when its only been 10 months but im a pretty emotional guy and get too caught up in feelings, so any advice or funny things to make me feel better?

Edit: Wow, honestly didnt expect this much, thank you everyone, this is honestly the best website community ive ever run into
