There are surely other platforms that streamline these things, but good luck getting everyone to use your service-of-choice. Just keep it simple, phone numbers and email addresses. Want everyone to see your vacation photos? Email a link. Aunt Bertha in the hospital? Call and start a group email discussion. Don't complicate things, stick to the KISS philosophy.
If you're spending too much time on those things, and that's what is taxing, just back off. If the people that are important to you feel the same way in return, they won't have any problem with that, because they care about you. If someone is high-maintenance, it's their problem, not yours.
...probably obvious and not what you want to hear, but there's my two cents.
