Is it normal to lie?

i have low self esteem. i just embellish details..i've been doing it since i was younger. for example, when i moved away from my old school i told people that i got free concert tickets because i thought they would think i was cooler. recently, i told my friend that i've been drunk before and made up a crazy story about it when it wasn't even true, later i felt bad and said my other friend made up the crazy story because i didnt remember. i've pretended to be drunk while talking to a friend because i wanted attention. i said i got into a certain college and applied to a certain college that i actually didn't while having an argument in a friend. when i moved to my new school, i told people i had had a boyfriend before, but then felt bad about it and tried to phase him out and really downplayed it once i made friends. i've never lied about anything serious, i just lie about little things...sometimes i'll post facebook statuses saying i'm doing things that i'm actually not doing. i'll feel really guilty when i do all of this stuff as well and either try to put some element of reality into it or actually do the thing i say i'm doing because i feel so bad. another example is, the other day i met someone at orientation, a girl who seemed really nice but was kind of intimidating, she was talking about how she was a varsity cross country runner. i was a cross country runner as well, but when we started talking about times i made it sound like i was faster than i actually was.

is this normal?
