Almost killed myself and nobody cares, nobody cares about me, why is my life like this?

So, I tried to kill myself and nobody cared nor even noticed. I attempted to do it in my bathroom. Social isolation, loneliness, social ineptitude, never having a girlfriend nor any romantic experience lead to that point. I need to solve those problems immediately otherwise I will die from them. Suicide would not change a thing apart from theoretically solving the pain, that is if afterlife does not exist. If it does then I failed god as a Christian henceforth then I’m an eternal failure. I’m a burden on my family and worthless as a person.
