as a very disabled person, online is really the only escape we have from stuff like pain and loneliness, however i can definitely see the issue. i'd suggest just communicating that you do want to talk to her more and miss your conversations. as for the topic of her talking about online interests and happenings, i think its just the same as any hobby, she's happy with it and that's good c:
it can be hard, i know that i put a lot of pressure on my family, but its about compromises and communication.
