Gerascophobia

Today I was able to contact a very dear friend of mine whom I've known ....since I was born!
Even though our discussion didn't last for as long as I'd wanted it to, it was definitely encouraging and helpful. We talked mostly about the future- what we expect, as well as hopes and dreams for our own futures.
(Although this might contradict my previous post, I'll push on anyway..) In about a month, I'm going to be 18- another milestone to add in the archives. I'm finding it more and more difficult to accept that I'm reaching this "independent, responsibility-prone"- age, Hey, I might be having a teenage-crisis (ha-ha). My big concern is what I'm going to do with my future, (again, this contradicts my previous post), I've always been a headstrong girl, knowing what, where and when, knowing what I would do next.
I suspect I've been shielding this anxiety from myself for quite a while, but since I can't be a little girl anymore, it's been showing itself bit by bit lately.
My plans have always been to complete high school and move straight into university.
Unfortunately for me, there are gazillions of universities I have to pick through, and even more courses to study.
My priorities have been shifting around lately, and now I have no idea what I want anymore. Can it be that I'm a Hypengyophobiac (fear of responsibility) or Maybe I have Gerascophobia...(fear of aging).
