my life isn't perfect but its really really good but i still feel empty

hey,

i(F25) have a great life. small but solid circle of friends. loving family who care about me. i studied hard, became an engineer, worked hard, earned lots of money and im doing my masters now. i have lots of hobbies, i am socially involved in uni and everywhere else too. i work out, eat clean, recovered from an ED. i would say im average looking but i have great style and i know what makes me look good. have a decent body. seemingly from outside, my life is perfect.

but i cant help but feel empty everyday when my day ends. im seeing someone casually, and most times i would come home i would feel anxious and empty. i thought this was because he is moving away soon and i brushed it off really. but then today i had the most perfect day with my bestfriend, and i still feel empty right now laying in my bed.

i just....i dont know what to do. i cant afford therapy rn since im paying for my uni myself and its expensive. but i dont know how to feel better. i sometimes feel like its the city i live in. i was born and raised in the city im still in it. or maybe its the lack of deep romantic love. i feel unrest and unsatisfied with my life and i have no idea why that is. im not ungrateful. i do appreciate everything god has given me. i rly do. but why do i feel so....empty. i feel horrible complaining about my life.

people told me to keep myself busy, have hobbies, do this do that. i do everything and still without fail every night i lay in bed i feel like crying. i feel this weight on my chest that i cant get rid of. idk what to do.
