Why do I feel so ambitionless?

Why do I feel so ambitionless 🙂?

Soo I m 22 , and I do prepare for some govt. Exam but I don't know why that I feel Ambition less . I don't dream of doing anything in life , I don't feel like achieving something will give happiness to me , i can't make relationships may be I m too egoistic to approach people . I don't let me to live with myself , keeping my mind distracted from phone . I was quite a good student I have cleared few exams also but nothing feels like doing something would give meaning to my life .

Please someone guide me out .I feel bad about myself when I see people in beautiful relationships ,having hobbies ,happy but I just sitting in my room listening to some philosophy or scrolling or some random podcast . I used to gym but lately from 3 months i have left that also , i go library for studying but there also I just waste money and days. I don't know where will I end up too .
