Lately I've been struggling with finding out who I am. Like that sounds so cheesy but I seriously am tripping, my boyfriends little sister who is 15 is the person I'm comparing myself to CONSTANTLY, LIKE SHES A KID. what am I doing!? I'm 21 so I know this isn't normal lol.

Some days I'm jealous of her or some days I try to "one up" her by dressing up, putting on makeup and being extra (example would attention seeking behaviors) 
Then there are the days where I feel like the most disgusting and ugly creature
.. 
I can never tell who I am, this weird kind of emptiness.

Sorry this was all over the place,  I was super embarrassed and ashamed that this is my biggest struggle now.
