Hey there, Crescendo,
Saw the video--yes, it's really hard work. It's very frustrating at times, and having constant remarks from family members doesn't help.
How long have you been trying to lose weight?
You have dropped 9 pounds--that's good! But people don't usually notice until you're down 15 or so. That's been my experience.
You aren't losing weight to make them happy, remember that. It's for you!
No, losing weight won't solve all your problems--just major ones like reducing risk of high blood pressure, heart attack, diabetes, early arthritis... things like that.
There are many inspirational stories here, in the Goals forum and Mini-Goals forum for example.
Keep going! don't give up!
