Tengo orgullo de mi (misma) = it would be "I'm proud of myself". Como en muchas otras expresiones, lo que en español se dice con ''tengo'' en ingles se traduce a con el verbo ser/to be. (ex: I'm hungry/tired/scared/etc). Se puede decir: I've got pride/I have pride, pero en este contexto seria para declarar que una persona tiene orgullo. Por ejemplo, si alguien se siente ofendido por algo, puede responder con eso. ex: If you need the money, just ask your father, he will not hesitate to help you. -I know that, but it is not that easy, I've got pride, you know! :)

"I was very proud of myself!" would be the correct way to say. instead of "very" you could also use "really" or "so". Congratulations on achieving your goal!

Thank you Christine!! :D I appreciate all the alternatives you gave me ^_^
