Sometimes I feel guilty for keeping my dog because of all the shelter dogs that need homes rn

This is just a vent/want to know if anyone has had similar thoughts or feelings. I love my dog very very very much and I’ve gone through great lengths to manage her behavior and be able to keep her and those around her safe. She is dog reactive/aggressive and I adopted her from my local shelter during the pandemic. The shelter dog crisis around the country is breaking my heart in a million pieces and I often find myself feeling guilt that I keep my dog when there are dogs at risk of being euthanized or who do get euthanized who don’t have the same problems she does. I can’t help but think what if I should be saving one of them? BE is not a consideration for us right now because what we’ve been doing (medication/training/general management/muzzling) is working and I think we give her an amazing life all things considered. Has anyone else felt this way? Am I insane?
