Echoing a lot of what has been said and adding:
You're in college. That tuition that you're paying offers you the services of the counselor/therapist on staff. USE IT. Seriously. That's what they are there for; to offer unbiased support to their students in need. Right now, hon, you're in need of someone to listen to your feelings, even if you feel at this point that they are "rambling." (We all ramble.
) The counselor/therapist will be able to present you with ALL of your options and offer support as you decide whether or not to tell those close to you and when... etc.
Hang in there. And use the services made availabe to you!
