If there's no way out- for whatever reason- eg. we feel compelled to carry on for the sake of loved ones. We know practically that we likely won't CTB in the foreseeable future- eg. for lack of reliable, peaceful methods, fear of an attempt failing etc. And if we know we also don't have the energy or resources to try and improve our situations, maybe we could be more at peace with trying to accept our circumstances. But, I guess it depends on how much someone is suffering. It's hard to put up with chronic pain for example.
Accepting your situation can also trap you where you are. That's ok if you can be genuinely content to stay there but if you're not, it can just lead to further anguish later down the line. As in- I'm still alive and still in this miserable situation because I didn't make any effort to improve it- because I 'settled'.
As awful as it is, being unhappy/depressed I think is similar to physical pain in that regard. It's our system telling us there's something wrong in our life. What's wrong likely depends on the person and what they want/need in life but- ignoring that and settling isn't always for the best I think.
Sometimes, I just think it kicks the can further down the road and when we catch up with it again, we now additionally have remorse that we didn't act on those feelings when they first came up.
Of course, the really shit part is when you have a strong suspicion that your problems aren't particularly solvable. I imagine that is the case for most people here. Then, I guess it really is a case of- am I willing to put up with whatever life this is? Not everyone is.
