Completely discouraged

I have been with my fiancé for a 3 years. We are both very much inlove. I have a 7 year old from a previous relationahip. We have been ttc for about 2 years. I've have hpv for 1 year and recently my obgyn has told me I need to get the leep procedure. I still get my period every month spot on. I can tract it by the hour! My fiancé and I are heavy set and I'm wondering if that's the biggest challenge right now. To eat healthier and lose some LBS. I lost my grandmother and with my depression I've lost 12 pounds but I need to get it moven! Can anyone relate? I just feel like I'm alone

And my bf just goes with the motion.
