I don't know how things can be remedied if you've already bleached your skin and now it is uneven, except to wait for time to renew new skin to the surface, and leaving it alone is the best thing to do.
Accepting yourself and loving yourself is of the greatest importance, even with uneven skin tone.
If you really think it needs "something" I would seek out a 'professional' opinion such as a dermatologist or skin specialist rather than doing it on your own. Enough damage done I think?
