I can't stop thinking about suicide?

I'm 18 male. I have been CHRONICALLY ill all my life. 24/7 fatigue,dizziness,migraine,brain fog,eyes sensitive to light,dry eyes,depersonalization(I feel disconnected from my body and things feel fake like a dream and sometimes I truly can't tell),reynauds,bad knee,bad joints,sensitivity to comfort(actual medical problem with feeling unfomfortable,like having to pee a often,clothes feeling too uncomfortable,and I can't sit or lay still...which worsens my sleep insomnia),sleep insomnia,eating issues,depression,anxiety,and much more such as lung issues. I had a partially collapsed lung twice...same lung both times. First time was chest tube to drain air. Second time was chest tube and lung surgery which involved cutting top part of lung off then stapling it then attaching to back of chest wall. I have blebs(Air pockets) on my left lung too. I am damned. I lost my life years ago. I'm already dead inside. I saved for months to buy a car and got my permet. Now,I can't drive since I feel like ****!!! I want to die. I'm sorry for the HUGE explanation. I'm tired of people dismissing me. If you see my story,you should understand. I guess I'm just venting. I self harm . I punch my head too. I think I hurt my jaw permanently. Anyways,thanks for hearing me out.
