I highly second the "longer meditation sessions" thing since I had a similar experience. I feel like many people are giving up on meditation too early, saying "it doesn't do much for me", without ever really having tried it. I spent one year meditating for 20 minutes each day. It probably did make me happier, but not in a dramatic way. Then I went on a 10-day silent meditation retreat and started meditating 1+ hours a day for a while and got dramatic benefits to the point that I feel like picking up meditation is by far the most impactful thing I've ever done to improve my well-being.
Well, but of course not everyone is in a position to meditate that much.

This is amazing! Reading this made me very happy and more hopeful for the future!
