Analysis of Love? Pain? Whats the difference?

In my opinion,
love is the most draining and painful emotion one could feel.
As you grow up you see all these movies/shows about how people fall in love and where they're happy at the end.
Unfortunately, that's not what it's like in reality.

Love isn't pure happiness.
Yes, it comes with a tiny package of happiness
but what people don't understand is that it also comes with pain, regret, vulnerability, insecurities, overthinking, and way more.
It gets to a point where your emotions are suffocating you
And the worst part is you won't want to stop it.

I've felt the feeling of love once.
And I'll tell you that tiny package of happiness it came with made me happier than ever,
but the pain that I felt in those moments is unimaginable.
I would never want to feel that again
