Ah things happen, I don't know the story but I do know that whatever the mistakes one makes cannot be erased, however, at least we have the option to choose to be better, and learn from those mistakes as to not commit them again. It takes a lot of time and willingness to do so. It's not easy but it is rewarding. From what I take, you are a dad and won't be able to be part of your daughter's life... however, keep striving to be better and better for your daughter so that you can be part of her life.

Go for nursing? May be? Or keep pursing your dreams? Give your best everyday so that you won't have regrets.
