Jeez, after i read this post. I know it is been toughest for you to survive through the years that you had. Now, you're in long distance, proving them a wrong where you have success through, and you're happier where you're in at this time.
Im truly sorry what happened to you but im proud of you what you've been through by STRONG. I admire for that. Ok, just dont look back in the past and just look beyond of the future what you desire to step. Just give them a love such as beginning: mail a card, "i love you, family" something like that. Just give step by step to grow. If i were you, i would show up funeral to prove them that i love them. If i dont show up, it'll HAUNT me for rest of life and itsnt funny. Up to you, ma'am.
Good luck to you both for future.
