6 Month Countdown

so here it is, 6 months before my departure date. i had this whole trip planned out. just needed the money. and what the hell? all of a sudden, it's muddled and confused. and i have no idea what i'm doing. the more i do towards it, the more things seem to crop up that need to be done.
jesus, it's so overwhelming, i wonder if i'm making this twice as complicated as it really is. god knows i have that gift, but damn. do i take my computer? how do i check email? what kind of camera do i take? what insurance do i need? shots? visas.
and by the way,
WHERE AM I GOING?
i'm so scared of traveling alone.
people post all the time that they are going traveling, and they just go. there's not all this drama. they don't 2nd guess and anaylze themselves over it. they just GO. why is action so hard for me?
i'm going in circles furiously
