Welcome from another newcomer!
I am in a similar boat to you as well... Started up a blog to lose weight and I lost 40 lbs but lost steam for about 3 months where I ticked back up a little on the scale... Now I have about 50 more pounds till I hit my goal. I just challenged myself again to lose 40 of those pounds in 10 weeks.
I lost my first 30 in about 8 weeks without exercise in a supervised weight-loss challenge at one of the local YMCA's. I lost 10 more the following 3 weeks and then I stopped for the holiday season from easter through new years and then through my Birthday in March... My original goal was to wrap it all up by March... now I am trying to kickstart things again in April.
You will get there... get to the point where I have gotten... don't hate yourself... but hate being fat.
Good luck bud!
