Being the youngest kid yet I grew up to act like the older protective mature brother

It's very weird like i was so close to him in my childhood, then idk how he drifted apart and became so distant and he's always so defensive you can never have a normal conversation with him.

I have become very understanding and close to my sister but my brother is just not doing anything about his life, he did whatever he wanted academics wise.

Career wise he did as he pleased and he has been doing just freelancing for a year almost being jobless.

He doesn't put real effort and tbh he's really becoming a failure.

He is 24 and yet he hasn't grown in his career. He isn't mature and he never takes responsibility, he doesn't even speak for himself like how is he so irresponsible.

Even though being so emotionally sensitive wanting to be loved, very early I had to become matured.

And even though being the youngest my personality has grown out to be like literally even like the eldest.

I'm 20 still.
