Coping is a skill, but healing is the goal. Imagine someone drops a large boulder on your shoulders. Coping would be to use all your energy and strength to avoid being crushed by the boulder, but what you ultimately need is to get it off your shoulders. No matter how strong someone is, the weight of the boulder will eventually exhaust and crush them. And if you have zero strength (no ability to cope) the boulder will crush you instantly anyway. Coping not something you can do indefinitely, but it's necessary because healing is a process that takes time, so we cope in the moment and try to work towards a more permanent solution.
Personally, therapy has been incredibly useful. I know some people here have had negative experiences with it, and I understand their scepticism. I've been very lucky with my own experience. What made me want to recover was, I guess, coming to terms with the fact that I'm probably not going to kill my self in the near future, so I may as well try to turn things around and do something meaningful with whatever time I have left here.
