Can't get a job 😞

I've been applying for jobs for almost a month now and I haven't been called in for an interview yet. My SO is in school and has a job and we're still getting by but I'm really sad I haven't got a job yet. My son is 2 months and I really need to start working. I'm also 18. I don't know what to do 😞😞😞😞😞
