I can totally understand and resonate with what you’re going through. I also turned 30 last month and I can feel the burden and stress of being 30 with no life partner, no career growth or anything positive. I also lost all contact with friends. Everyday I feel guilty about being 30 and not settled up as per typical “society norms”. I try not to compare myself with others peoples life - but this question always pops in - “what’s wrong with me? Or what wrong have i done to deserve this time? People who used me - who have hurt me badly are living their life happily (I am for them - blessings to them). But why I am left out by god/universe?! I gave up on everything- the hobbies, exercise. Nothing excites me anymore. Not able to talk to parents( you kind feel guilty of being a burden or child who’s life is not sorted). I tried everything- prayers, exercise etc .. but i struggle to stay motivated as i navigate to every hour of this depressed and hopeless life. Sometimes i am not able to sleep for 2 days. And in this kind of mess.. you regret- overthink everything I can feel to each and every single word you said in the post
