I don’t want my life anymore, I have no self-confidence , I have very little faith

For most of my life I’ve never understood why it was the way it is, I’m not comfortable in my home it’s never been completely finished all my life which bums me out a lot especially sense I have friends i don’t feel comfortable ever hanging out at my house, My Mom and Dad Also Argue a lot which I hear so much I’m to the point if they ever got a divorce I wouldn’t care if anything it would make me more happy. I’ve had no feeling towards God or Christianity in almost a year, I’m a high school student and I even go to a Christian school and I’m only 16 years old and I never thought I would feel this way which is no feeling at all I lost all care for God I’ve been emotionally drain for the past 6 months my mental health is slipping.
