I just returned yesterday from hiking 66 miles from Mt. Washington to Grafton Notch. Yes, you are tackling one of the hardest sections of the AT. Since you asked, if you are new to hiking and going alone, this is a bad idea and you are in over your head, IMHO. Is it safe? Not compared to most other sections of the AT, no. Elevations are not only extreme, but near-vertical on some pitches and go on for one-to-two thousand feet in places. Yes, you can fall down the mountain if you take a mis-step.
If you'd like to see some photos, here you go:

My advice? Head to Georgia and see how you do. Closer. The bus ride will be bearable. More reasonable for a novice. And still a heck of a lot of fun. And that other section will be there next year.
If you do go, I recommend the White Mountains Lodge & Hostel on the AT just outside Gorham as a great place to stay, ship a box to, rely on for a shuttle to town, get to know other hikers, etc.
