Hi Kellie! What's your goal weight if you have one in mind? I am right in the same lovely big boat as you - I started at 344 lbs last Sunday and have managed to get to 333 this morning.
I kept giving up too, because having a 150+ (200 lbs for me) weight loss goal can be so overwhelming. This time, it's just different for me and I know I won't give up - for 3 reasons
1) I set up mini goals instead of seeing it as 200 lbs to lose. Right now my first goal is to get to 299 lbs. 34 lbs to goal? I got this!
2) I don't deprive myself, and don't overdo my exercise. So many of my past diets were me eating as little as possible and trying to exercise every free moment I got. I eventually crashed and burned and got sucked back into my old habits. Right now I am doing cardio 4-5 days a week and for about 1 hr - 90 minutes a day. I am eating healthy foods but am incorporating things I love. I love ice cream, so I am having a skinny cow or weight watchers ice cream every few days as my treat, and I work it into my calories.
3) I use clothes, activities and my son as inspiration. I'm always thinking of what I'd like to buy myself or what I'd like to try (like ziplining) once I start losing weight. It's something to look forward to and keep the motivation going.
And 4) is just an added bonus - I TALK ABOUT WHAT I'M FEELING. I never before wanted to discuss my weight loss struggles because it was embarrassing especially to those I assume could never understand because they've been fit all their lives. (which could be wrong) but still, it's so nice to come to 3fc and talk about the struggles, the successes, the questions, and get kind, encouraging feedback.
Welcome and congrats on taking the first step. I know you can do it, you'll get there - we both will!
