You have enemies? Good. That means you've stood up for something, sometime in your life.
- Winston Churchill
Not every body will like you, you will always have those who dislike you, that life,
you will also have those would do like you and actually appreciate it dude.
Also going back to what the minge said
If you don't want criticism, then there's your flaw. Also don't take this to heart, it's criticism that bites.
Hes right you need criticism in order to help you out, i don't know your story and what these people have been saying but mabey you should hear them out on what they have to say who knows you may learn something.
