I was you at the start of the year.
I'd gone from a slim 8/10 bright blonde confident sexy young woman.... to a size 14/16 bloated middle aged frump.
I was three stone overweight (conservative answer, more like four)
I was wearing shitty clothes that were ill fitting and scruffy because I wasn't me. My hair was a mess and I wasn't taking care with my makeup.
My DH was sick of it. He was sick of me moaning about it and being depressed about it.
I was forced into needing new clothes, as I changed job (not in the best Circumstances but wow such a positive change)
I'm now a size 10, four stone lighter , my hair is accidentally looking awesome and I've literally just bought an entire new wardrobe and loads of makeup.
Started: new cloths for work.
Eating less because I had less time to eat, was stressed and lost my appetite.
Increased activity level meant the weight fell off.
Husband took me to MAC for a makeup lesson so I revamped my makeup.
I emptied my wardrobe of anything that didn't fit (at the start) and that I was using to hide in. Replaced worn out underwear and tankers.
I literally had five pairs of pants, one pair of jeans, some work clothes and three vest tops. But they all looked better on me. Which marginally improved how I felt about myself.
And I built from there.
Just as one drop of water will erode the cliff, as a PP said, one brick built the Great Wall of china.
Start with something that gives an INSTANT boost, paint your nails....get your brows shaped, anything at all...and build from there.
It will come good.
Focussing just on weight loss is a losing battle ultimately because it takes too long, you stall and plateau and lose motivation. So you need a multifaceted approach which delivers long, medium and short term gratification.
