Old age/Death

I'm 18 and have been worrying a lot about getting old, death, and time passing in general. I definitely don't feel like I've reached that "getting older" stage, but even thinking about how I'm inevitably going to reach it upsets me. I have a lot of friends who are in their mid 20's and I see them going through "I can't believe I'm going to be 30 soon" and then I think about how they aren't that much older than me, and that I'll be going through that soon as well.

I made another post recently involving using my time wisely and trying to be productive, and that is strongly tied to this.
I've sort of worked through the "wanting to be productive all the time" problem, but I still feel like I'm having a mild mid-life crisis, only I'm not nearly middle aged.

I don't have a specific question, but does anyone have any advice/comments on this?

Hey,

It's perfectly normal to worry about this, and you are doing the right thing in talking about it. I'm 27, but I have already realised that we only get one shot at life. Growing old doesn't weigh too much on my life, but I do try to make the most of everything that I do. I 'dive head first' into things (more or less) so that I can have as much experience in my life as possible. I suggest that maybe you could try this too? - i.e. becoming more 'ad-lib' (or free) and adventurous. When you are old and are looking back on your life, i guarantee you that you'll have been happy that you tried everything, instead of backing out due to nervousness, shyness, fear, etc.

Hope this helps.
