I beilive that suicide is wrong depending on the contexts of the situation. If a teenager wants to kill theirselves over something that is temporary, then yes it is wrong because there are other solutions. In your situation I think that it is justified. I would watch the documentary "How To Die In Oregon" and other movies about assisted suicide, so you know what you're getting yourself into. I would research a lot about assisted suicide and the availability of it near you or near a country close to you. It might make you feel better just knowing that you have the option. Talk to your family members about it. Let them understand your pain, let them know why you beilive it is your only option. Let them prepare themselves. If I love someone and it is truly something that they need to do, because they can't live another second on this earth, because of the physical pain, then I'll understand. I won't be happy, but I'll get it. I'm so sorry that you feel this way and I'm sorry that it could be your only option at this point since it's permanent, but remember the people you're leaving behind and handle the situation as gently as possible in fairness to them. If you ever need anyone to talk to on the phone or text, feel free to message me. I don't judge your decision, because in the end of the day it is YOUR choice. I'm personally an Atheist.
