Lost my friend of 4 years

Lost my best friend of 4 years after coming out - feeling lost and heartbroken. I'm completely reeling. I finally came out to my best friend of four years last week. We've been close since we met in school. I was so nervous, but I built up the courage and told him I'm gay. His reaction wasn't outright hostile, but it was... distant. He said he needed time to process, which I understood, but then he just... disappeared. He hasn't answered my texts or calls. I also tried to meet him by visiting his home, but his parents said he wasn't there (he probably didn't want to see me).It feels like he's completely ghosted me...

Honestly, I'm devastated. Losing him feels like losing a part of myself. Four years is a long time. I knew there was a chance he might not be okay with it, but I never thought he'd just cut me off like this. Has anyone else gone through something similar? How did you cope with the loss of a friendship after coming out? Any advice would be greatly appreciated. I feel so alone and lost right now.
