Should I disappear from friends?

I looked through their current posts (on facebook) and when I saw how great they are doing right now, including how they are physically...I feel that...like it's totally the opposite for me and I am struggling and it's not going well.

Like not on the same level with them.

Feels like it's better if I disappear from them.

I did unsubscribed from their posts but a part of me still cares, so I went to their page and saw their new posts.
