Is it normal that i just randomly block everyone out of my life?

I have a large family with 4 sisters and they all live in the same small town. I moved across the country and only speak to them on the phone about once a month. I love my family, but their lives revolve around religion and I'm agnostic so I feel uncomfortable around them. If you are avoiding them for a reason similar to mine or you have some unresolved issues with them dwelling in your subconscious, (especially from childhood) then you need to address those issues with a counselor, or with them, so you can break down the barrier. If you avoid them because you enjoy being alone then explain to them that this is the case. This removes the cause for them to suspect that you dislike them and they might be more understanding. Also know that reclusiveness is a symptom of social anxiety and depression. If you feel you may suffer from these disorders, please get professional help.

Sometimes we need to be alone

Yeah I do it often I just have moods where I don't want to speak to anyone or be around them but then a day or two later I'm okay

Yea I do this too. It is bad I know, but sometimes keeping in touch to the level they want me to seems so tedious. Sometime I also don't know what I would share with them anyway.

I'll do this to family and friends for random reasons too. Sometimes u just gotta take care of urself and pull away from all that pressure
