Welcome!
Joining the site is definitely a great step in your weight loss journey. I'm new too and everyone has been so friendly and helpful, it's really motivating.
What has worked for me in the past and seems to be working at the moment, are small goals and challenges that aren't overwhelming. Like, cutting out (or even limiting) one or two foods that weren't doing me any favours (pop and chips). And trying to fit in more exercise. I used to think I didn't have time for it. Turns out that if I switch off the tv and make an actual plan to exercise, I have plenty of time
You might want to consider having a goal like "lose 5 lbs by Easter", or "get 30 minutes of activity in each day". Doesn't necessarily have to be the gym - yesterday I hauled wheelbarrows of wood around and stacked it, and dug holes in my yard. Exhausting, but nice to be outside, and definitely a workout. Even something as small as commiting to taking the stairs at work every day is a great step.
Good luck!
