I'm at the beginning of a weight loss journey and I could use some encouragement/advice

I had a "come to Jesus meeting" with myself about my weight last weekend (mothers day weekend). Me, my husband, his best friend, his girlfriend and her son were all at a local theme park and I realized I was too big to ride any roller coasters.

I broke down. I feel like I've always known I needed to lose weight, but now it's taking things away from me that I love (roller coasters).

Also, I've been told that losing weight would help us conceive. We've been trying for roughly 8 months now.

Pretty much I was just hoping for some encouragement or advice on starting my weight loss journey.
