Poem 1: "I knew this nice girl, but I was afraid to ask her out. I lose."

Okay, I sympathise with you, man. But rather than writing bad poetry about it, why not tell yourself that, hey, the next time you see a girl you like, why not ask her out?

Poem 2: "I have no self esteem, yo"

I sympathise with you. But this the best place to adress this problem?

Poem 3: "Dude, where's my self esteem?"

Do something about it. Try to find something which makes you feel proud of yourself.

Poem 4: "Did I tell you how little self esteem I had? Oh, and by the way, I really like the word "lost""

I'm sorry, but your poetry is rather tragic, and not in a good way.

Poem 5: "I lost my self esteem. Or wait, did I ever have it?"

We rather got the message by now. And... Well, it's fine if you like to express your lack of self-esteem creatively -- but most people would, y'know, keep this a secret and not post it on the internet?

Poem 6: "Why won't women love me? Don't they know I have no self-esteem?"

Poem 7: "If I wait long enough, perhaps a woman will love me. And then I will have self-esteem."

Or how about working on the self-esteem bit first, and then women might, I don't know, feel more comfortable around you?

Poem 8: "Mankind is lost. So is my self-esteem."

The former is out of your control. The latter isn't. Please, find something which makes you feel better about yourself. Something which does not involve showcasing your lack of confidence to the world.

Poem 9: So utterly tasteless I won't even bother with it. Seriously... I am ashamed of having even seen it. Maybe you had good intentions with this, but don't you find it rather tacky to use such a tragedy to draw attention to your poetry?

To summarize my feelings about the poetry; please, man. Stop trying to showcase your self-pity, and get out into the world and actually do something about the problems you are facing in your life. If this does involve writing self-deprecating poetry about yourself, then at least keep it in a private diary, and don't post it on the internet for all to see.

Peace.
