Can you convince me there is a point?

I was thinking about time and how every second gone, is gone forever. I just realized that it keeps flowing and won't stop, or repeat. When you're on your death bed, you can remember those experiences, but you can't experience them EVER again. What makes it worth it? I believe that people can believe any philosophical doctrine, however different, just not at the same time. I don't know why but any philosophical thought I have, no matter where the start, ends in nihilism. I'm open to ideas right now and I will really sit here and think hard, I just need some sort of reason behind it. I'm just scared because nihilism seems to be able to fit all of these philosophies within it but still make sense. I think about death and I get this feeling some of you may know. It's a feeling you could only have if you've come to the realization that you WILL die. If you've had this realization you'll know what I mean I think. I'm honestly just confused and sad. I feel like I'm going insane and things are getting less real. Reality seems blurry. It's almost like there's a haze over my life. It's like I'm just a little further away from life than everyone else, it's so hard to explain! I just want to accept anything else. Please give me any ideas, I don't care how out there. I'll do my best to understand.
