To get out, there are a few options, but they all are "cheaty" since you did not bring a linking book:

1) If you enabled cheats, do: /tpx 0

2) Go to NEI and change the setting to cheat mode, then get a star fissure block, place it down, and step on it

By the way "Age 105" is the name of the dimension you are in, not how old you are :)
