I wouldn't necessarily take this as a sign they don't care. I have a story for my own experience in this.
I took a massive overdose in my mid twenties. Would have been successful but my best friend found me and called for help. Fast forward an induced coma and a week later and I come round in the hospital.
That same friend was supposed to come visit me about three days after I woke up. He didn't show, and I was devastated. Eventually my parents and his wife managed to get him to come a few days later, and he was really closed off, like he didn't care.
We were stood out the front of the hospital having a cigarette, and I straight up asked him what was going on. He told me that he just couldn't deal with this situation. He thought he was going to watch me die, and it was destroying him. I'd never really seen him cry, but he cried so much that day. That broke me more than anything else.
I know you must be in a ton of pain, and my heart goes out to you. But its's possible that your friends feel pain over it too. And maybe they can't face or handle it.
Just a thought. I truly wish you all the best. This life is so damn hard.
