I want to pour the bottle of drain cleaner into my throat.
Don't do that!
I wanna die. My life is a lie!
Killing yourself with drain cleaner is not the answer. Just think of all the people you will leave behind, and you will see that there are reasons to keep living.
Only my dad cares.
Then think about your dad before you do anything drastic. Call him up and let him know how you are feeling and you can talk it over with him. Whatever problem you are facing in your life now, it will not last forever, and you can get past it.
