How do you cope?

So there are billions of galaxies out there, with billions of stars, and around some of those stars is planets, and some of those planets have to be like Earth. Diverse ecosystems and species, one dominant species with many different cultures and languages, landmarks, and everything that Earth has. Somewhere out there right now, this exists, a planet like Earth yet at the same time, alien and new to our eyes, with species unlike anything our brain can comprehend. What do some of those species look like? I don't fucking know, it hurts my head just trying to imagine what they could look like, and what their languages and everything like that would be.
Even worse, they could know just as little as we do, and they could be thinking the same exact things I am right now. Or they could be incredibly technologically advanced, to the point where they have seen other species and the idea has become accepted, and part of the norm. We don't fucking know! We know it's out there, but that's it. This is driving me mad beyond belief, how can I go on living my day to day life or even doing anything when I'm consumed by this great desire to see what's out there? Hell, just looking up at the stars at night brings me to tears, because I'm looking at it. The worst part is that I know that in my life time, I'll never see it. It's out there and it's very real, BUT I WILL NEVER FUCKING SEE IT. That is the most depressing thought I can possibly have. And this is just on the physical realm that we can see, don't get me started on what's beyond that, and there is something.
It's just, my life just feels so pointless. In my lifetime no breakthroughs in SETI or whatever, and I'm going to die at the same exact point I'm at now with all of this. And after death, who knows? I guess death is a release, either I move onto the next step in existence and see and understand more than before, or there's nothing. Either way, this poisoning curiosity I have will be quenched. So in a way, I'm looking forward to death, it will set me free from all these thoughts I have. But I can't look at things that way, I don't wanna waste one second of my time here on Earth, in case it's all I have. So my question to you is, how do you live your life regardless of all I just said? Is it possible to accept it, or do you just have to ignore it? Please help me, I feel like I'm on the brink of madness here and I don't wanna go off the deep end.
tl;dr: How do you live your life day to day, regardless of the fact that there is so much amazing, uncomprehendable stuff out there in the universe that we will never understand??
