i don't have much time left

i don't know what it is, but i hope that i'm wrong. something's telling me that i don't have much time left. PLEASE don't take this as a way to look for attention nor that this is a plea for help! I'm fine. I guess it's because of my birthday or some mid-age thing, but i don't want to take whatever time i have left for granted. i'm planning more trips. i don't want to be "live" at work. i want to tell my friends how much i appreciate them. sometimes, i feel like i'm being too much, but shoot, i don't want to let a moment go by to not give a present or a compliment to someone, because it might be too late. i'm just... trying to love life and the people close to me as much as possible. the problem with this is trying to love myself just as much as i love everything else.
