Uh, I must be dense or something but I'm failing to see the bad part of this. You did what you had to do for your kids and are still a part of their lives. More than my mom ever did for me (I was adopted at 6 months and have no idea who my birth mother is).
IMO, it takes a great deal more love to give your children up so they'll get what they need, then to keep them and be limited in what you can give. (if that makes sense)
Anyway, I don't hate you, or think any less of you. And I don't think anyone else here does either.
We all still

you!
