I sleep for hours everyday, don't leave my room unless I have to use the bathroom, I don't socialize with my family at all even though I'm a very social person when I'm not as depressed and when I do I don't speak in a very happy tone of voice but it seems they are too busy to really care or pay attention to details like that. I would rather show them because it's just very hard for me to talk to them about it. If I were to email them they'd just talk to me about it in person even though I feel sick to my stomach when I talk about anything too emotional. I actually remember one time telling my mom I felt suicidal, but she said we couldn't afford any of that treatment for me which I know is not true. I don't think they take me seriously and I want to show them it's serious.
I understand. That's a situation that many of us can relate to unfortunately.
Have you ever attempted before? I just want to point out that if your mother uses money as an excuse, and if your family really doesn't care at all about you, trying to do this in a dangerous way (overdose, jumping, hanging, etc) and failing will prove them right and cause you more trouble down the line. They will come up with more crap to blame on you (unjustifiably, and at your expense) and your problems won't go away.
so your family is clearly not going to listen. How about emailing your psychiatrist directly? Or leaving them a voicemail? Or calling a hotline? The people at a hotline will only ask for your location and call 911 on you. You can even walk out the house, start walking and tell the people on the hotline that you're walking on your way to kill yourself. You will still be hospitalized, it will still be a big deal. Probably some bad things will happen, or some good things will happen, or both. Who knows? The point is that you *kinda* don't want this to be the end, since you're hesitating and asking for non-lethal methods.
You're still very young, and you haven't finished school yet. You don't know if your troubles will ease once you get away from your family (if they really dont care about you, then they will welcome you leaving to get your own apartment or go to college) and it won't be fun adding a stomach pump, broken legs, paralyzed, brain damage, etc... to your medical chart. Don't think about what that means to anyone else. Think if that's the kind of life you want to be living.
Think about this please, and think about what you will really achieve. Make this kind of decision for yourself alone.
