How can i improve myself?

I’ve been trying to improve myself for now like 2 years. Ab I dont know kya and kaha galat karra hu. I’m(M19) 53kgs and around 5’11, bhot zyada skinny hu. I got no fashion sense either. I don’t know kaise upgrade karu in chizo ko. I’ve been working out for 2 years or so now and zyada kuch farq nahi aaya hai. Ek Last try karna chahta hu kaise karu? please help.

Calorie Surplus ka pata hai and abhi mai pichle ek mahine se hu, 1kg gain hota hai fir agle din wahi 1kg kamm bhi hojata hai. Pehele diet ke sath consistent nahi tha, ab ho raha hu time time ke saath
