Feeling exhausted today...

Life has been so tough, and still I've tried insanely to keep on top of what I can, but I am in physical and emotional extreme pain and nothing is giving in. I try to stay focused as much, distract myself from my own emotions and problems whilst also having to cope with alot of physical pain, very alone and supporting my mother too. It just feels so havy at times, and I am here just sitting on my feelings, trying to keep it up and focus on whatever I can to keep going but today is a tough one. What do you do to keep going? How can anyone want to keep going when all you do is having to keep beign so resilient all the time? I feel exhausted and wondering how much can I keep this going :( Any good recommendations for distractions online? Thank you all in advance.
