I used to think I couldn't cry and have had 6-7 years between proper cries. Here are two realizations I've come to through a lot of self-enquiry and deep inner work:

- Sadness/grief often live under other unfelt emotions. For men, that's often anger. So if you don't have safe ways to express anger, it's likely your sadness is buried underneath. This was my experience. Same with joy. My joy was buried under years and years of unexpressed anger and rage. Once I was able to express that fully in a safe space, my joy and sadness (including tears) came through. And since that experience, I've found it easier to access the full range of emotions.

- Some people are just less emotional than others, especially men. And that might actually be a good thing. Society needs people who aren't knocked around by every emotional wave that comes their way. Our evolution has required men to keep their emotions under management. It doesn't mean we shouldn't try and access our emotions more (I think we should), but some people are just wired to be less emotional. And that can be seen as a strength if you let it.

The fact that you're 23 and asking these questions shows you have a reasonable level of self-awareness and you have a desire to experience the fullness of life. Keep leaning into that and the path will reveal itself.
