Of course, you can always come to Spark for support & motivation!
There's a saying: "Wherever you go, there you are."
Meaning, the one commonality of wherever you go, whatever environment you live in, be it where you are now or half way around the world, alone or with others - is YOU.
YOU get to decide what degree, if any, you will *let* the outside negativity affect you.
I framed the word *let* because I know it isn't always easy! Stuff happens, and sometimes that "stuff" may include naysayers.
Try your hardest not to let other's negativity get you down. I found for me, anyway, it's imperative I stay as positive as I can. Like the others mentioned, think of why you are doing this; know you are so worth it, and imagine yourself so proud when you achieve your various triumphs. Make sure you celebrate/ reward your achievements! Post them on the Woo-Hoo board so we can cheer you on.
Who knows? Your post could inspire someone else!
Speaking of, do read & post to other's msgs on the msg boards. It not only cheers them but benefits you. Keeps you focused and on track.
Read all the success stories and envision that one day, that could be YOU.
