Planning on running away

Okay, first off let me say I'm not being abused in any way. I love my family so much. I'm just bored, and nothing's changing. I'm so close to suicide that I figure why not give this a shot, it might help, it might not. Either way, I tried. I want to travel for a while, learn to be independent. I want to learn how to be on my own, how to not rely on my parents so much. I have a backpack full of stuff that I could use; self defense stuff, first aid, tools, etc. I still have to pack my clothes. I do plan on coming back home. Is this horribly selfish? I mean, I feel like I need this. I need to get away and at this point it's not going to happen unless I do something about it. Don't lecture me, please, as you don't know my situation, nor do you know me. I'm just asking for advice.
