Problematic Habits

Well, I am a young man, I have never been one for parties, nor for wanting to be intimate with women, nor for having any strange vices, basically I think that my entire life has been very calm when it comes to those topics. I have mental fog

But I feel like I have VERY bad habits.

I just want you to tell me

How bad is it not to have sun, to be locked in a simple 4x4 room, not to exercise or do physical activities, not to have social interactions for a long time or social activity, to spend so much time on the cell phone (I don't have social networks except for YouTube and reddit), and to constantly pmo??..

Be VERY honest, if I could receive recommendations or help
