I think I may end it tomorrow?

Hi. I'm 18 male. My life sucks. I'm sick. Mitochondrial disease destroyed everything. 24/7 fatigue,dizziness,migraine,brain fog,pressure in head,eyes sensitive to light(worsens migraine),dry eyes,reynauds,bad knee and joints,spine has partial arthritis which will cause future issues,sensitive body(food texture,the way clothes feel against me as in they can't be pushing in one area of my back when I'm laying down or underwear annoyance and always have to pee),sleep apnea,confusion(I feel like I'm in a dream a lot due to everything,things always feel fake and I doubt this reality as though it's a dream.),etc such as recent lung issues(pneumothorax/partial lung collapse!). I had surgery first time it happened this August, that was just chest tube to drain Air. Second time 2 1/2 weeks ago was chest tube and top of lung cut off and lung stapled then attached to back of chest wall. I bought my first car and got my permit. I quit driving a month ago thanks to brain fog almost making me crash. I need to die. Please help and feel free to really explain. Not short messages saying "it gets better" because that probes you're stupid and don't get that "THIS" won't get better. Thanks
