Facebook doesnt work that way. You cannot 'restore' groups to a new profile.
You have to readd all friends, groups, events, calendars etc. when getting a new profile.
You can do this, but you cannot 'transfer' info, posts, people, groups etc from one account
to another. You can make a back up once you gain access in case you want to save all your
fb communications thus far, but you cannot merge accounts.
What you should focus on is the other account. Also, if FB catches you with 2 accounts, they
will hit you with authenticate the account and make you 'choose' one of the accounts, if not delete
both your accounts.
We need to go in and find your old profile and try to figure out what email you used for the other one
and gain access to it.
When you are ready, let me know.
