I always fell like I am "not enough" regarding everything

This feeling appears when I am at the university, when I am at home, when I am with my friend_s- actually wherever i go or whoever i am with. It seems like no matter how hard i try i'll never be able to be good enough in anything or to anyone. It causes a lot of anxiety and stress- especially the thoughts that i do not have some sort of stability because of this. Seems like i do not have enough energy to do anything everytime i push myself to work/to look good/to be friendly.. I cannot get this emotional rest (??not sure how to explain) because there's that feeling that i cannot be myself- i cannot be accepted without always trying hard.

I understand that i cannot be the best in everything but i just have the feeling that i need to do more, i need to try harder, i need everyone to respect me and when something goes not the way i imagined it- i am becoming afraid. I am trying to work with such thoughts as soon as i notice them but i just feel so tired and useless. It's like in that meme 'i just wanna be...appreciated'...haha

Sorry if it doesn't make sense but thank you if you read this :)
