I'm going to avoid talking to someone and ignore them
Why are you going to give this person the cold shoulder?
I don't like talking to people who are creepy
If the person creeps you out, it's OK to avoid them. Is this something you could talk out?
I never talk out my problems, I rather kill myself then to face them.
I understand wanting to avoid talking with someone who makes you uncomfortable, but you shouldn't feel so anxious that you want to harm yourself. If you are truly having thoughts of self-harm you should talk to a therapist, or at least a close friend.
