I am 25 now and was diagnosed on my 18th birthday....HAPPY BIRTHDAY TO ME-total bummer!! I never had any symptoms until about three weeks before I was diagnosed. Went into remission very quickly after being put on meds and didn't have a major flare until this time last year (planning a wedding, dealing with my father's cancer and buying a house can really stress a person out!). I am almost in remission again so lets keep our fingers crossed!
Sorry for the babbling! :)
