You Are A Good Person.
You are working hard to do the right things, that is clear.

It will be best if you continue to try to get along with all your colleagues as you are doing now. Others teasing you is just something you have to endure. Sorry. You are doing well not to judge this boy too harshly. He sounds difficult to work with. Think of working with him almost as practice working with patients, if that help you. You are practicing your 'people skills" with him and your other team members, even when they are not there. That will only make you better at your job. Good for you for staying focused on the work.

Perhaps you can discuss with your professor or instructor how best to accomplish all your requirements to be sure you are doing everything you can to do well, with or without your team.

Keep up the good work! I think you sound like a good and compassionate person with a bright future.
