First, this is essentially a duplicate thread so I merged them both here.
As input to the OP, you initially were excited about receiving the scholarship, and suddenly less than 1 week later it's absolutely not for you. I certainly don't understand a transformation like that and can't imagine what may have happened to so turn you off. I certainly would expect some yelling the first week or so and would take it as something to persevere through. This is especially true if you have an "active" freshman orientation. You should at least give it a semester and I would give it a year, to help alleviate the financial implications of funding college without the scholarship if nothing else. It's way too soon to consider dropping IMHO.
A little story. My son's NROTC unit had a 5 day NROTC freshman orientation before anyone else had reported for school. It was lead by former Marine Drill Instructors. Orientation was hard. They definitely got yelled at. You can see it here:
The PNS spoke with the parents and the new midshipmen before carting the new midshipmen away to start their orientation. He then spoke with just the parents as a group and took us through what the kids would be doing that week. He made a point of mentioning that one goal was to get every kid to question whether he or she belonged there. The midshipmen were not allowed to speak to one another for 3.5 days, and could only speak to cadre when spoken to. 2:00 minutes per day were allowed for personal hygiene, etc, etc. On the last full day of orientation they went to a lake for a cookout, swimming, sailing, and were finally allowed to speak to one another. The PNS was right. Each kid found out that everyone there had thought about leaving. DS considered it Tuesday night while on fire watch but decided he would stick it out and show them he could do it. However, of the 45 kids who started, 15 dropped that week. BTW, the cookout is where the new class of midshipmen bonded as a group.... just the result the PNS was after.
I suspect you may still be in the "do I belong here" stage. I don't know which group you belong to... those who drop, or those who persevere. I do know that participation in the program isn't going to kill you, and whichever group you are in you will learn lessons about yourself, while participating, that will be useful the rest of your life. I hope you are able to persevere and get to where you can see the beneficial aspects of all this.
Hope you decide to persevere.
EDIT: I bet you admire your parents. Care to guess where at least some of their good qualities come from?
