There’s absolutely nothing to be afraid of here. This place is as safe as anywhere on the planet. You will be allowed maximum freedom, but you won’t be coddled. No one will take care of you, or make your path an easy one. To do so would be to insult you, depriving you of your dignity.
Here, you are free to change your mind, make mistakes, accomplish absolutely nothing for days at a time. You are free to reap just what you sow. If you are easily bored, you will be even more bored than usual. If you can entertain yourself, your time here will be well spent. A few small challenges will keep you busily occupied. Solving problems builds character.
There are others here who will be like you. If you are especially active, or popular, they will see you as a threat. They will strive to cut you down to size. Others will try to inspire pity in you, to entangle you in their chronic problems. If you are wise, you will avoid them. Do not give advice. Do not take anyone under your wing. You have no wings.
You’re simply an inmate like everyone else here. Accept that fact and your life will be easy. Fight to achieve distinction and your life will become a living hell.
