I think when I was 12 I injected a needle into my veins twice. I have been thinking about it lately.
Why did you inject yourself?
I thought it could help me grow breasts.
Injecting yourself is not a good idea. You do not know what was in the needle, or how to inject yourself properly. It can be dangerous.
You're probably right but it didn't hurt me so it's okay.
You are lucky you didn't do serious harm to yourself. You can't just do medical things to yourself without knowing what you are doing.
