There are a couple of grammar errors that I saw. In the fifth line I think burned should be burns. I think it would flow better to me.

And in the third to last line im should be I'm.

What I sensed from this poem though is that this person has lived a very hard life and now as they have grown up the bullying is still affecting them. I really like how you didnt hold anything back and wrote all of yourfeelings out. None of the lines are really that sloppy and flow really well. The very first line does a good job "ssetting up " the poem as a whole and asks a good question. "Will I ever be good enough" It's easy to doubt yourself when society has been mean to you over the years. I really think you did a good job writing what a lot of people with depression go through. It's a never ending cycle of everyday feeling sad. The ending line is good at wrapping up what you wanted to say. It's like laughing is the "final" step to getting trapped into the cycle of sadness. Good write overall
