It [censored] man. There's no way around it. You're still very early in the process. I don't think I really got a "good" nights sleep for maybe 9-10 weeks after BD. And even then, it wasn't consistent. I'm now out 5 months and overall sleep is back to normal but I still have off nights where I get maybe 3-4 hours. I also lost around 40 pounds in that first 2 months, and am now down an additional 10 pounds since then. Although the more recent weight loss was more due to exercise and slightly reduced appetite than outright starvation, which it felt like at first.
You are just past the starting line in a 26 mile marathon. I know it's hard right now, but keep following the advice you get here, the 37 rules, etc. Try to work on GAL activities, and you probably won't even enjoy them much, but do it anyway. You sort of have to fake it til you make it, which may take a few more months. All I can tell you is that, with time and effort, it WILL get easier. Only in the past week or so do I honestly feel like I have started to turn a corner and my days are overall more positive than negative. And as I said, it's just over 5 months since BD. So yeah, you may have a few more rough weeks or months ahead. Stick with the program, and keep posting.
