Hi,
I can reply to this but I don't think I'm qualified to be able to really answer, especially not on here. If you'd like I can give you names of people/places who you can email to ask.
In short, my view would be that making yourself a lake would mean to be looking at the bigger picture. Don't just see the pain. See the small things that you are grateful for. R', hmm, I don't remember who it was, was saying that he gave a class to people and asked, if you'd use the use of your feet who would still be able to be happy - some people put up their hands. If you'd lose ___ et al, until the last question, if you'd lose all your faculties, but could still think, would anyone here still be happy? One person put up his hand and said that he would. Because he could use his mind, and he'd be able to be happy because he is working with what he ha, and that's what he has.
I'm not putting it down very clearly, but the point is that there is so much pain, such real pain. Some situations, you should't just look at the big picture, but have to actually do something to change the situation, because it isn't safe. Safety is paramount. Even then, though, one can look at the small things they're grateful for.
This morning, for example, I'm grateful that I slept a little bit. That I feel asleep after I woke up. That it's snowing outside and looks stunning. That I've a bed to sleep on. That I like my bedding.
Sometimes, when I'm stuck in my head, I'll sit for 4 minutes writing what I'm grateful for. It really helps me focus on that rather than the other things. And when I'm in a better frame of mind, I can look at what the pain is and see if there's anything I can do about it.
Sorry for rambling....
