Hello to you!
I'm also fairly new to this site but in just the few days I've been on here it has really helped me out. You'll be surprised to find many people on here with similar situations to your own.
I would recommend trying some of the challenges they have one this forum. I entered the May one just the other day, I started dieting at the beginning of this month. From what I can tell, they do it monthly and it's just kind of a nice incentive and push.
I really hope you find this site as helpful as I have in just the short time I've been on here.
And of course, if you need help with anything or motivation, you can message me anytime.
