Christians and non christians I want to ask something here. do you find life sometimes gets you down to the ?

point it feels like running a marathon that keeps going? like pure exhaustion and you just keep trying to hang in there? Like you are waiting for the day you collapse and die? as something shuts down one day in the body right? and christians I am a christian so do not tell me to give my life to Yeshau when I have. anyway everyone on here please tell me if you feel this life is getting painfull to live in? I do. I do not know what is worse, a death sentence or living painfull. so anyways your thoughts on this please. cause I feel my life might be cut short the way things are going, as I would not mind as I know where I would be going. But how do you handle life, is it painfull for you too to live in?
