You are not the first nor last person to experience something like this. You could be miserable and do nothing or you can try to make your life better and be more grateful and simply try to backup everything. It is sad story but don't be harsh on yourself, easier said than done I agree. All I can say is you can still learn new things and get a better life. Who knows maybe you would have sold all your bitcoins when the price was 1k and now regret that even more. Thing is it happened it is the past, you still have time to make things right. Bitcoin is not the best opportunity of the century, there are opportunities around and you are the one who needs to find them.

Although I don't know if your story is true or not, since we had some people that come and tell these kind of made up stories, anyway hopefully this should be a good learning story to show new people that you want to have backups made, multiple of them and store in safe place if possible.
