I agree with Fuzzy. Try to be the best that you can be. You can't please everyone, but the one that you need to please the most is YOU.
Just remember, you are number one and you look out for you.
Let your parents argue. It doesn't mean that you have to listen, right?
I am sorry that you and Sparkling have never felt the love of another person.
Be patient. It will happen. Trust me. There is someone out there just for you. They may be feeling the exact same way as you do right now.
Good luck to you and let us know how you are doing.
Hugs,
Boopers
