Would you go on a college tour if you had no one to enjoy it with?

I’m in my final year of college, we have a college tour to Goa,Hampi and some other places. Till joining this college, I’ve always been excited for college or school tours, and the main part of the tour for me was not the destination but having fun with my boys. But now, Im planning to skip it. I have till tomorrow to pay for the trip and i cant take a decision.
Here are few facts you should know:

1.I’m 4 years older than my peers( i did a diploma that took 4 years due to covid;also there are people with the same age and above here)

2.Not one of them here are my type

3.I drink with friends, ONLY with friends and no one i am comfortable with here drinks.

4.In my og gang, we used to roast each other (‘ഊക്’ to be precise ) and each and everyone used to enjoy it, even the guy who was being roasted, but here, you can only do it so little, and after that they’ll feel bad and when they’ll internalize it and hold it as a grudge against you.

Because of all this, I feel like most of the guys I stay with in the hostel don’t really like me anymore. There are five of them, and over time they started hanging out without me. I slowly began feeling left out, and eventually it started affecting my mental health, which in turn affected my studies and my confidence. Now i cant even talk to someone while maintaining eye contact. Also, I think im even facing cognitive decline due to my mental state. I’ve tried going to a therapist but I couldn’t explain my situation to him clearly due to my fear of being judged by him.

At this point, I honestly don’t think I have anyone here that I can confidently call a friend.

Now the college tour is coming up, and I’m wondering if I should even bother going when I don’t have a single person to enjoy it with.
