Two tight straps and some bark marks sounds like normal tree stuff to me, not some big disaster. Unless the trunk is actually choking or the tree is tipping over, I would not stress about it. I usually pull stakes after a year and call it done.

My buddy went through almost the same thing at Toledo, did two years of pre-med because his whole family is doctors and he was dying inside. He failed anatomy twice and finally admitted to himself he was only there because of the pressure. He moved into marketing and it was like a switch flipped, he was running the student paper's ad stuff and actually showing up to class. His GPA went from like a 2.2 to a 3.5 and now he does brand work for a bank in Cleveland and makes decent money. The part that gets me is how long he waited because he was scared of what his dad would say. Turns out his dad got over it in like a month once he saw the grades.
