I'm sorry. But girl, you have to like open your eyes and head and come back to reality a little bit. Your asking how to kill yourself on a site called Medhelp?
That is obviously a cry for attention, not a genuine question.
There are no "strongest pills" that you speak of. Are you talking about a benzodiasapine or an anti-depressant? Because that only a psychiatrist could evaluate what is best suited for you.
Im very sorry your parents say your a bad daughter. But why dont you just prove them wrong instead of crumbling beneath them. That is a way more powerful statement than just giving up your mere...12...years of life on this planet. Now I know that this issue probably seems like the whole world to you but GROW UP.
If you get "top grades", your not cheeky whatever that means, and you do housework then your probably not really a horrible daughter and thats your parents being frustrated and telling you that in a poor way. They are human, and humans do f*ck up, even those who your supposed to count on.
Lets cut the drama, and when your ready to start acting above your raging hormones, post again and maybe some of us can be of more help rather than you asking a ton of questions how to kill yourself and then saying NO you dont need help.
Like anyone is going to advise you on how your going to kill yourself. Again, kill the drama, open your eyes a little, be a little more accepting, and when you have a real issue you want to bring to the table (which seems like you have some genuine issues we could HELP you with here) and your ready to confront it and not act like were 3 then post.
If you dont need help why did you home to Med...help
