My university has a general disabilities support group, but I agree with you that there should be more groups on campus specifically focused on dealing with type 1 diabetes. Maybe you could somehow connect with other type one diabetics and start your own club? Making friends who share similar struggles has been one of the most helpful things for me in dealing with this disease.
Otherwise, I think that joining support groups outside of your campus would be extremely helpful. I haven’t had experience with this, but I think that the benefits of this type of support group would be very helpful, so I’m looking into this myself.
