Anyone looking for a buddy

So over the past year I’ve put on a lot of weight. I’ve got two sons 9 and 5 at my heaviest I was nearly 17st, I got all the way down to 11st4, looking back now at my lowest I wasn’t over weight but I still felt I looked fat, oh how I wish I could be that weight again, currently 13st10. We’re trying for our 3rd but no luck yet, I want to get my body in the best shape possible but am struggling to lose weight. Really would love a buddy to give me some motivation and a kick up the bum when needed
