The Social Conundrum

I’ve been learning about authentic communication / relationships. In doing so, I’ve noticed increased feelings of loneliness. A while back I discovered that I have a deeper love for others than previously thought, but I’ve found that being authentic with people is not what they expect and is often misinterpreted. So I struggle with knowing how to express love and appreciation or even give a genuine complement. Is this due to a lack practice, or do social norms not allow for it? I guess there’s a reason that people keep their private thoughts private. Once again I find myself not with answers, but with questions.
