The way I've thought about it that helps me still want to pursue life despite nihilism is the idea that I think by itself, 'experiencing' is more satisfying to me than not 'experiencing'. I used to think because existence necessarily included pain, it necessarily was worth avoiding, but I came to what felt like a helpful realization in the idea that 'when I'm dreaming, it doesn't matter whether I'm experiencing a painful/hopeless/threatening/scary situation, or if I'm experiencing something good, or if it's just neutral; I think I'm always more satisfied having a dream than I am not'.
I don't know how many people can relate to that, but that idea is what gives me hope that there is a way to be at peace, or appreciate the experience of existing/having sensations, even if that entails some amount of pain/discomfort/suffering -- enough that I'd rather experience things (even if there's pain) than experience nothing.
And as I've had the time/space/support to pursue it, I've been finding a lot of reassuring things in Buddhism (and it's cool to hear others seem to as well) that do make me think that if you can get past your ego (treating yourself with compassion and acceptance, recognizing thoughts as thoughts that you don't have to attach yourself to, trying to bring your focus to the moment and the sensations/energy of it, and nothing more than that -- appreciating the pure fact that you're able to have any sensations), existence is something that is something that I appreciate enough to not pursue ending it.
I think the other side of nihilism is deciding how you want to guide the direction of 'your dream/life'. Technically, you could do whatever you want, end up in any situation, and still probably be able to appreciate the moments all the way up to the end. But if you think about yourself, there might be some sort of experience(s)/purpose(s) that you're drawn to -- that you'd like to have or like to move towards. This might be what actually justifies you 'putting in effort' or actually doing something to move your life in a direction.
As I'm working towards a place of appreciating/understanding and accepting/pursuing life, I think the most satisfying way to guide your direction is to find something that makes you feel good at the mere idea of doing anything to move towards it.
And as I've been told, and found the most satisfaction myself, the most long-term satisfaction/experience that you'll want to pursue probably has something to do with contributing something of yourself to the world/or something that impacts others.
