Talal your post was amazing and I am so sorry for what you are going through, both with your lack of affordable care and the experience of having to deal with your cancer every day. I know it must be hard on so many levels.
Watching this thread, and if there is any way for me to donate, I will. I am not well-off, but would gladly find a way to help out.
One thing I can say confidently: Your life till now has not been wasted. We all have dreams we don't reach, but just being alive for a time is a gift. Every second we gain a wealth of experience and add so much to the world that would not exist if we didn't.
Lots of it might seem minor when you compare it to personal built-up expectations or the VERY small minority of successful, well-off, and/or iconic people upon which we tend to frame our notions of relevance, but it's NOT. Every second you've lived to this point right now has been a supernova of relevance because you ARE and have been. There is a kind of binary logic going on here, in that there is infinite nothingness, and then there is existence. You got to be part of a tiny minority that is existence, and probably affected that for others more than you think.
All the more reason to fight, and to ask for help as you can. Even if it ends up not working, you will have spent your days here fighting to stick around, and can pass knowing that you celebrated and appreciated your life.
Wishing you the best and hoping I can help, bud. <3
