Nothing as crazy as the other posts. I feel lost as a person

Just my rant, for context Im a 23 years old male. Student.

Lately I have lost the energy or the intrest to talk to other people. I picked a lot of trust issues in the past 1 year since I moved out the country.

I barely let anyone in. Pretending with even roomates.

Ive trying to put up a strong front that i am emotinally unfazed and shit like that. Now im starting to belive fake it till you make it is True. Now I barely truly let anyone in, Talk naturally to people. Ive just become a hollow man. I feel this emptiness. Ive been smoking more often lately. Trying to understand what kind of a person I truly am.

The world is so fucked up, if you dont act strong or show strength they walk all over you. And once they know you are strong they wait for you to make a mistake. Ive gotten exhausted proving to others what I am capable off. Honestly Nothing excites me anymore. Ik for a fact I can get anything academic or career oriented done. I dont doubt it. But im lost as a person. Had I had a gf would i be doing better? Idk to have gf, I need to be able to talk. I forgot how to talk like a normal person. Idk myself anymore

I dont even know if I make sense. But i wanted to put it out there.
