I think my bullies ruined my whole life
How did the bullies ruin your life?
I feel insecure around other people.
You should not let past experiences ruin your future. It would be good to get mental help for your situation.
They are mean but I'm no stranger to being hurt emotionally.
I am sorry to hear that you've been bullied for so long. Try to move past them, surround yourself with people who care about you and their support can help you to heal from those emotional wounds.
