Nick, don't you DARE do that.
Suicide is a permanent solution to a problem that is, truly, temporary.
The transgender issue aside, the unhappy home life that you are describing is something that MILLIONS of young people endure, whether children, teenagers, or adults. You are not alone in that. Grin and bear it for now. And if you want to go the extra mile, then make a gentle effort to allow YOUR own light and self-awareness to enlighten the lives of the troubled people around you. Offer words of genuine kindness and encouragement to the people around you who don't necessarily deserve it, and watch them soften. You yourself can be an influence on them, and help them in THEIR personal growth. Instead of engaging in anger, try killing them with kindness in the face of their insensitive and dysfunctional behavior.
Nick, please do NOT do anything rash like attempting to take your own life. Suicide is a very dark road that leaves a trail of pain and devastation, and your own soul will be so disoriented and damaged that the pain you are seeking to alleviate will endure on a different plane. Don't allow your feelings of anger and hopelessness to dictate your actions. In moments of stress, leave the home, go to the edge of town, and take a walk in nature...for as long as you need to. This will lower your stress levels in a big way, and connect you with the natural world, putting in perspective the temporary nature of your current crises.
You are a smart, aware, loving person, who is worthy of companionship and connection and you WILL find it when the time is right. So don't do anything stupid. *big hugs*
