There's nothing wrong with being unhappy, IMO - you can still channel those emotions into something meaningful.

But if you do want to be happy, you can find stories, if you look hard and long enough, of "outliers". People who, against all odds, defied "statistics" and broke out of whatever expectations society and "facts" projected onto them.

I tried "everything" until age ~27 when I finally found one dial (very specific elimination diet) that made the rest of my body act mostly normally. Other changes were easier to make from that point onwards, altho there's a lot of damage to undo still. Diet is just one factor, for others it could be completely different.

My point is - I thought I would never be healthy. This stuff runs in my family too. But I just kept trying things. There's no other option.

You are a unique human being and soul who has something valuable to contribute to this world. Even if that's being unhappy.

Hope that doesn't sound condescending, it's something I tell myself too.
