Keep talking to us. Holding painful feelings inside just adds to the pain. You can expect people here to try to lift you up or offer alternative perspectives. Maybe that will help, maybe it won't but it may be a good idea to at least have a place to process how you're feeling.

No, you do not need to move to acceptance of a forever end. You need to accept that this is a phase that will end and not last forever.

Keep looking forward. Distract yourself mentally and emotionally as much as you can. I'm not sure what your doctors say, but sleeping through this much pain seems like a natural response.

I know it must be hard to have to lean on others. Maybe it would help to pay it forward a bit. If you see a thread here and you have insight to offer or encouragement to give, that is a form of service. I know I feel better about being in need when I can offer something at the same time. No service is too small. Simply sending one good thought to someone who is struggles is valuable.
