As others have said better than I ever could, until you are mentally ready, any excuse will do.
You are putting off dealing with this. I did the same, put my life on hold until I was thinner. And I was miserable 24/7 until I finally did something about it.
Eventually you will run out of excuses or have a health scare.
Do you cook from scratch at all? The enemy is processed food. Bread, crisps, biscuits and chocolate are my downfall. Ditch alcohol, diet drinks, processed crap, ready meals and takeaways for one day. Then repeat.
Set yourself a goal of 30 days. You might cave on day 2 or 3 at first, but don't beat yourself up.
There's a Chris and Xand van Tulleken BBC podcast about processed food that is helpful. There's also a book just out:

Get some rest. Instead of binging, go for a walk. Or give yourself a manicure, do a jigsaw, read a book, take up knitting or crochet. Or batch cook and freeze some healthy meals as a standby, if that's possible.
You can do it, because I did. And I used every excuse in the book. Tried a different new diet every Monday and fell off the wagon by Tuesday. Steadily gained more and more weight. I had a wardrobe of lovely clothes that didn't fit, and lived in leggings and baggy tops. I thought I deserved the junk that I ate as a treat or reward. Then I realised that feeling great was better than all the cake and self loathing.
Apologies, that was a bit of a brain dump, and I hope it didn't come across as patronising OP.
Good luck.
