I was baptized as an infant too.
I have not actually been baptized as an adult but have wanted to since I started to learnn infant baptism isn't really baptism in middle or high school. I almost did in college, but held off. I still haven't. I don't think the time is right yet. There is something I'd like in my life, & I struggle w/ 'is that a reason I I want to get baptized? If I didn't want that would I still get baptized or would I consider my infant baptism sufficient?'. & like OP, I'd feel like I'm stabbing my family in the back. It's not meant to be a secret.
OP, I actually disagree w/ 'getting baptized right away' or 'in 1 year I will.' This is big decision. This isn't something that's done on a whim. As an example: too many people think they're 'born again', get baptized, only you find out they walked away from the faith completely at some point. They will say they were baptized, but the truth is, they were just going off an emotion. I'm not saying this will happen to you, & that you're not saved, only you really, really, need to think about this. 'I have a new attitude towards old sins' or 'an experience' isn't what being born again is. It's recognizing that you as part of mankind in your own sin was an enemy to a holy God & rightfully deserved judgement, & he thru his bloody death on the Cross as a sacrifice in your place & resurrection back to life, took your judgement, so now you are God's friend & have his promises so desire him as he's revealed himself.
It's not an atittude b/c attitudes can change. It's not an experience b/c those can be forgotten. It's a knowledge & an acceptance of that knowledge. This is what we mean when we say 'believe.' It's not like 'I believe I'll win the lottery.'
