I had the same question.
When I started asking myself the point of things, rather than finding answers I just found myself eroding all sense of meaning away. Nothing I could find seemed to have any real meaning at all in the long run, and the more I looked for it the more everything started to feel empty.
My whole life I had assumed things had meaning, but now that I was looking for it it wasn't actually there. It basically made me miserable.
I did find an answer eventually though. From almost all angles, I couldn't say why it was better to be alive rather than dead. Anything for my own sake was completely ruled out, because I wouldn't need it if I were dead. The trick was to think of perspectives that would persist irrespective of my own continued existence.
Although it doesn't matter to me if I improved something versus dying, it matters to all the people who wouldn't be dying. Although I can't say that I'm better off for existing, other people are better off for me existing, and given that I care about those people, there is meaning in my existing.
What underpins all of this is the belief that it really matters whether people are happy or suffering. Not just matters to me because I currently exist and hold certain values, but really matters. Some people seem to doubt this, but I don't. If I think about a pet or a family member, there's no way I could say it doesn't matter whether they are happy or suffering, and if I ask myself the reason it matters, it's not because I just happen to know them. If I never existed, it would still matter. It matters forever, independently of my own existence.
Once I realised that I believe it really matters how other conscious creatures feel, it was easy to see the meaning in everything. It matters whether I stick around to help people. It matters the impact I make or don't make on the world. It matters whether I'm happy, whether I improve myself, whether I act or stay in bed, because these things help me give value to others.
This answer stuck with me, and it's been years since I had any thoughts questioning the meaning of my life, what I'm doing or my journey. I couldn't be further from nihilism.
I don't wake up every day trying to help as many people as I can... but I know that my life improves others' lives in small ways, so there is a quiet confidence carried with me that my existence matters.
