I would second the advice to talk to a priest if you're genuinely troubled, and take the following advice for what it's worth, me being a regular kinda lawyer but not a canon lawyer ...
"Canon 1156 §1. To convalidate a marriage which is invalid because of a diriment impediment, it is required that the impediment ceases or is dispensed and that at least the party conscious of the impediment renews consent."
"Canon 1157 The renewal of consent must be a new act of the will concerning a marriage which the renewing party knows or thinks was null from the beginning."
The fundamental question is actually what you were thinking when you convalidated. If you were insisting on wearing a veil and on consummation, not to mention thinking of changing anniversaries, it sure sounds to me like you were sufficiently aware that your first ceremony in some sense wasn't quite a 'true' marriage - which I should think would be enough for the convalidation to be valid.
At the same time, the language used by the Canon is 'renewal' of consent (implying that consent was actually given in the initial marriage, and is somehow given again, but this time in a sacramental way, at the convalidation).
