I can really relate to you. Lemme tell you a little about myself to show you:
My mom gave me up at birth to my grandparents. I never really thought about her and never had gotten anything so much as a card from her. I didn't have her for it, because not matter who gives you a life to thrive in, its a life. But my grandparents didn't want me growing up with regret so they sent me to live with my mom. We didn't get along at all. Its hard to relate to someone that gave you up at birth and had 2 more kids a couple years later and raised them. I was constantly lying to her about everything because I felt like it. Eventually I read her diary where she talked about me. Everything she said made me DESPISE my existence. Our relationship got to the point of physical contact and her hating me. She took me out of school because of my bad grades and had me raise her children for over a year. I hated myself, her, and wanted to end it ever s badly. But one day about 6 months ago I realized that the only one who can determine my life is me.
So onto you and your question. KILLING YOURSELF IS NOT THE ANSWER. Speaking from experience in that category, its a pointless thing to do. Sit down and talk to your mom, there's some backbone to the reason you've been constantly lying to her. Go to therapy with her and see if that doesn't help. Your dad taking you out of school because of bad grades is stupidity. If your getting bad grades he should be encouraging you to get better ones and helping in any and every way. Maybe you should tell him that, and actually TRY in school if given the opportunity to change his mind. As far as living in a city you hate, make the best of it. Because when you realize that your SO MUCH MORE than how you feel at this moment...you'll thrive and you can accomplish things that will bring you one step closer to happiness, and maybe even an apartment or house in a city you'll LOVE in the future. Future is the key, and the hard work and dedication you put in are the mechanisms that that unlock it. You can't see what your future holds if your not here love. Don't kill yourself, its not the answer your looking for.
