Do you still feel connected to the world?

I am considering getting rid of my facebook because I find that I get such bad facebook depression. I hate that I look at people's happy pictures and posts and feel so much jealousy and resentment. I know objectively that my life is fine and that people only put forth the most positive story of their lives ... but my brain is irrational.

So if I get off of facebook, am I going to feel disconnected from my friends' lives? I have no other social media profiles. I've been on facebook since the inception and I don't even remember how I felt connected to the general social world without it. I'm really bad at keeping in touch with people outside a small group of close friends so I'm worried I'm going to make myself feel even more isolated somehow...

(Oh and I am 100% aware that I am overthinking this. Just curious what your experiences have been)
