I feel so overwhelmed and need advice

I would like some advice on how to manage stress and loneliness and anxiety about future.

I'm 27f , doing a job, I'm stressed about my career and life, I don't have friends, no love life. I feel so lonely. I'm often overwhelmed overthinking and cry everyday. I'm open to talk more if anyone can listen to me, currently I need advice on how to manage stress and anxiety. I've started to try to get up early for workout. Evening after work I want to work on side hustle or study but I feel so damn sleepy early like 7pm I don't drink tea at that because I plan to sleep by 11 and get up at 7.

I would like to understand how to manage loneliness because I tend to waste a lot of time talking to strangers alone or resting because I feel so mentally exhausted unable to focus on work.

I can't afford the therapy so please help me out..
