Welcome to the forum, kenny b. The time around dx was one of the hardest for my son. Things did improve but it took some time.
Did they start you on Pred/steroids while you were in the hospital? The steroids will generally help things improve quickly. Somewhere during the steroid taper they start maintenance meds as well to give them time to build up and take over when you have tapered completely off the steroids. This will probably all be discussed at your GI appt.
Things do get better, once in remission things will improve greatly. I hope you find remission soon, if this is IBD.
