Here we go again!!

hi all! My name is Laura, I'm 24 from UK, and had my first baby 6 months ago. I was a bit overweight when I got pregnant but now I'm a stay at home mummy , I just munch all day and have piled weight on. I think I might have mild post natal depression- I could take my son for walks everyday to try and stay healthy but I don't want to go out by myself, I have zero confidence, zero self esteem etc. I'm embarrassed of myself.
- So it's time to act now. I am going on our first family holiday (myself, partner and son) in September so I have my goal date to lose my ideal amount of weight. I really need the motivation and having someone to talk to here who feels the same would be awesome.

I've tried before to lose weight and it was working but then I just stopped, then fell pregnant and I'm now the heaviest I've ever been and it has to change.
