I will probably commit suicide later on

I don't think I will be able to handle and live this sort of life of loneliness, singledom and celibacy forever. Yes I can probably go on for 40-50 years more while being severely depressed, miserable and perpetually frustrated. But when I do get to that point, I won't have anything to live for. I don't mean I will use a gun or hang myself or anything like that. I will have nothing to lose at that point. Nothing will matter anymore. So I will probably go do some stupid, dangerous and risky things like extreme sports, fast driving, getting into dangerous situations. Because why not? What's the worst that is gonna happen? I will die simply. Unless Allah by His mercy accepts my duas to make me happy while being single for the rest of my life.
