Let loose

I notice myself being uptight sometimes...idk why though...I want to be able to just let loose and not care, but sometimes, I care lol! I sometimes feel worried for what ever reason...but I now see, hey, Im 21! I can do as I please! Alot of people around me have attitudes that I adore, the whole "Live free & dont give a fuck" attitude...and I do have that mentality sometimes but not as much as i'd like...
