Hey:
First thing, I fight with my parents too (specially my mom) and that happens to everyone, wether you're 15, 19, 22 or 30 years old or whatever, wether you're boy or girl and wether you're straight or not. That never goes away.
Two, how is killing yourself gonna work at all? I mean, ok, you won't get the bad part of life, I get that... But what of the good stuff, what about your parents, do you really think they'd be better off without you? They've fought a lot to get you wheree you are, they've been with you for the goods and the bads... and you think they'd be better off without you? Answer to yourself this part.
Finally, I wasn't planning to answer to you this part, because this part of the 10 nicest things in the world are really subjective and different for everyone, but let me tell you my 10 best things of life:
1. Life itself: I often wonder how amazing life is, it's just plain great. I love life and I love living it. It's a constant danger, a constant joy and the best of all, constant dares. I love dares, I love the risk of life, definately I'd miss that a lot if life just flew past me.
2. Love: It took me a long time, but I think I'm really close to love and be loved, I definately wouldn't want to die without knowing what love really is.
3. Hugs: I just LOOOOOOOOOOVE hugs. I couldn't stand living without hugs... I just like to hug and be hugged. It's like really good, warm, I don't know, it just makes it all good when you're hugging someone or being hugged.
4. Friends: This one is complicated to put into words, but it's just great to have friends that really care about you. They can help you a lot whenever you want them to, and can actually do pretty much everything for you.
5. Games: I just love to play games, any game, almost anything, but just to play and entertain me a while, of course, playing with friends helps too XD.
6. Medicine: I couldn't live without it (Technically, nobody could xD) I love it, I love thinking medically, I love listening to hearts, I love examining patients, I love learning about medicine, I love medicine and that's it.
7. Sex: This is pretty self-explainable, it really doesn't need much explanation. But sex is good, making love is better I guess, but sex itself is pretty nice.
8. Music: I couldn't live without music, music really gets me up anytime, I love to listen to most types of music. Glee music, pop music, rock music, metal music, latin music, hell even salsa is good every once in a while. Music gets it better almost always.
9. Family: I love my family, each and everyone of them, I know that they love me too and care about me, and that the'd be there for me for almost anything. They are the best ever, and I have learned not to take them for granted. Enjoy your family while you can.
10. Myself: I love me, I just love me too much, I couldn't kill myself cause I love me, I've learned to love me and I love to love me. I'm happy of how my life turns out, even if something bad happens, cause it gives me the chance of being better. I love my mind, I love my body, I love myself. I just love how I worked out to be, cause I'm the result of all the other 9 things mixed up together.
I'm happy to work through every bad time, good time, or whatever, cause it gives me experience and tips to learn how to live better, to learn to love me more.
Remember what Frankie (Frank Sinatra) said "I live it my way". Whatever you do, any decision, any thing, do the thing that pleases you most for real, love who you want to love, have sex with who you want to, go to where you want to, marry who you want to, do everything to get it good for you, to be HAPPY for real.
Don't do anything you'll regret, you're a great person, you're just a little confused. I love to help you out whenever I can, but I'm no expert on depression or stuff, my recommendation would be to go to a speciallist to work on your depression, and hopefully one that's not a priest. Really, they may be or try to be good people. But they can get everything to confusing or be really extremists.
I hope I helped, I really do like you dude, take lots of care and please, write to me a lot cause I'll try and help you whenever possible.
Kisses
Juanchi
