In need of support my dog that I’ve had since I was 7 is gone

I’m now 23 he was my first pet. Im shaking as I’m typing this because I can’t think he’s had a lot of issues really old and he died at my home. I am in shock my first pet that I adore and love so much my love is gone. I have 2 other dogs but it’s not complete without him I just can’t believe this i want my baby but now there’s nothing I can do to bring him back he was so beautiful and loving I just can’t accept this I can’t even look at pictures of him right now how can I deal with this :””””(
