I feel different, more "normal"

I used to be a very fun person to be around. Very witty, almost invincible in the mind game. I took everything in a fun way and I was very open minded. I could easily socialize with anyone. Although all these "superpowers" weren't there for me all the time, I can say that I had them

Now, even though I have evolved as a human, I don't feel like that person anymore. Even when I feel at my peak, still,I think that I can not compare my current self to my old one.

Jokes don't come naturally and when they do, they are not at the level they used to be. I feel like i lost my emotional intelligence.

I also feel very tired and unmotivated most of the times. I have no depression, maybe the exact opposite. I don't care about anything (if that's a hint)

Coffee, exersice, cold exposure, sitting and doing nothing in my room and a little bit of going out of my comfort zone are my ways to try and reach my old self, with some success but not all that much.

I can easily say that I have converted from a way above average in intelligence person to a way more "normal". And normal is boring.

Any help will be very welcome. Thanks in advance.
