Get active. The absolute worst thing you can do is “nothing”. You will feel so much better getting out there and doing good work with your neighbors. Looking for local mutual aid orgs in your area is a good start. If you can’t find any, start one yourself! Another commenter here goes into greater detail, but you can start very small! Or arrange some meetups around skill-sharing. You probably have a useful skill or knowledge that others could benefit from, and I’m sure there’s things you’d like to learn as well. Doing things like this builds community bonds, and strengthens us all. Don’t wallow, get involved!
I hadn’t looked at FOSS image album software in awhile, but I recently installed Immich on my home Yunohost server. I am very happy with it so far. It is miles better than Nextcloud photos, and I’m honestly blown away by how well the facial recognition works. I’m also enjoying the “x years ago today” highlighting feature, after seeing proprietary platforms have that for so long.
