Struggling to stay motivated

I started in June last year and had managed to lose 11kg which broke 2 of my goals but after Christmas I got sick for nearly 2 months and managed to put 6kg back on I've lost 3kg of that but now I'm really struggling to get motivated again. I was doing so well with eating and exercise but once I got sick I couldn't exercise and I was binge eating between naps. Now it's hard to get back into the healthy habits also everything hurts now since putting the weight back on. I originally wanted to lose 20kg in 12 months but now I have just under 4 months and 11kg left. I need motivation. I don't want to give up. I don't want to hate myself anymore
