Love

Love is what you do, not what you say. That means love is a verb that expresses feelings, not an adjective that describes them.

I love very strong. Most people don't show love how I show love. That's why even people I haven't spoken to or seen in a while still know I love them, because I showed them love unlike what they are use to from most other people. It wasn't just words.

You wonder why it seems like nobody loves you, most likely it's because you don't put out love. You're most likely harsh on yourself, and so you're the same way with others, or even worse with them. In other words, you can't love anyone else because you don't truly love yourself.

You can't curse or treat someone (or even yourself) badly or harshly if you truly love them. How is that? Because harsh words or actions don't even stem from love, they stem from hate. To hate something or someone is to wish to avoid them, as in feeling like "I wish I never met you."
Now discipline can stem from love, but even that, if it has love behind it will be gentle, not harsh or extreme and pushing the person further from you.
