Weight loss

I'm so jealous of all you women that have posted about Losing 100 pounds in 6 months or a year...ive been trying so hard for two years to lose just a couple of pounds. I've changed my diet and started going to the gym but nothing is working and I'm losing hope. I'm done trying when nothing works but I've been wanting to have a baby for two years and that's one reason why I haven't given up yet but it's just so hard to keep going when I'm not seeing any results.
