TRT & Improvements in emotional flatness

I’m not 100% how relatable this may be but I wanted to ask.

For a little background, my testosterone I believe has always been low. I found out from my doctor that my testosterone was low in my mid twenties (314). I’m in my late 30s now.

I remember vividly getting really excited about things, feeling true joy during special moments or occasions and just overall having the ability to experience a true FULL range of emotions. Even the feeling of love feels a bit fleeting (not to be dramatic).

It’s been an extremely long time since I can remember having these feelings. I just feel emotionally flat and have been for more than a decade.

I have always attributed this to low testosterone and it affecting my brain on a chemical level somehow.

Can anyone else relate to this with true low testosterone? If you are on TRT how long before you noticed your emotions returning to normal?
