I'm the same way. I was diagnosed at the age of ten but went my whole life until the age of 33 before i did or went to a doctor about it. I've been on sixty mg of adderall a day for like five months and it has its ups and downs. I guess it all depends on whether you want a definitive answer or see about getting on medication. If this new situation is effecting your social and home life then i would at least want a diagnosis. Then i would say go from there.
