Feeling lonely and helpless

Basically the title I (M26) am working as freelancer and staying with parents. No social life. Friends have dropped me from their circles because I Don’t make money like them and cannot afford to participate in the activities they like to indulge. My parents are supportive but they’re very old senior citizens so I Don’t want to burden them with my problems. Mentally I feel very unstable all the time and get random episodes where I feel people are following me or insects are crawling on my body. I want to stop this and function like how I used to function normally free years ago. But I have no one to talk to.
