Back again.. feeling bad

So. I haven’t logged on for over a year but today after someone commented I was looking “pudgy again” I stepped on the scales. I massively got upset because not only have I *gained weight* - I’m also now heavier than I’ve ever been before in my life and it just crept up on me. I know I’ve been doing things I shouldn’t - eating ice cream, too many snacks, crappy meals. But i didn’t realise I’m now 5kg heavier I was last time I started losing weight, and 5kg heavier than I’ve ever been in my life.
I need some help getting back into it. If anyone wants to friend me on here or knows of any groups. For reference, I’m not *quite* overweight however my waist circumference puts me in “very high risk” due to my body composition and all my fat going to my tummy.
Please someone help me stay on track this time as I’m starting a new job in October and I don’t want to be a pudgy one, I want to be at least back to my previous starting weight before I start my job.
