Tangential plug, I launched my own social network without feed, notifications, or even a way to find people there. It flopped everywhere I promoted it, but it is still online since I am on free tier of the host service. If anyone wants to check it: https://www.quidsentio.com
If you have a social network like you made it requires that groups of people join it together, and that they know the other has it in advance, and that costs money to post beyond a certain number of posts - it's not clear what that they can get from you that they can't get from facebook or instagram already for free. It's not clear what you're offering that's better than those two.
The features of 'no feed, no notifications, no way to find people' isn't necessarily a plus to the overwhelming majority of users, and from your page I don't understand what you offer in your service that even someone who journals wants.
