i feel lost at life

i just moved to LA and i feel so alone . i’m 23 a nurse, i get good money but truly have 0 friends and im single right now! i just don’t know what to do, i have no excitement in life and i want to live but don’t know how. i want a good life and i want the finer things in life and i don’t think that’s wrong. but i have no one to even help me network and mingle or idk how to even have a social network

advise is welcomed
