You probably feel that way because you're taking it to mean that you've failed at life. You said yourself that you hate having to live with your parents and that's understandable. I think your mind is actually taking it as a defeat. It sounds like a case of Learned Helplessness, where you feel like you're in a bad/threatening situation that you cannot escape from.

What you can try to do is set small goals for yourself that will let you see that you AREN'T trapped at your parents' house. Little savings goals or even interview goals. "I'm going to rewrite my resume by the end of the day based on some guides", "by the end of the week, I'm going to get feedback from at least 2 people on my resume", "I'm going to apply to at least 5 jobs that I meet qualifications for by the end of the day", etc. You can even set other goals like, working out for 30 minutes today or reading through a guide on Sharepoint (or some other useful office tool that you can add to your resume). Small goals that you can accomplish within the span of a day or two. When you start accomplishing some goals, you will gradually start feeling more confident. The confidence will boost your motivation and energy gradually and you'll start feeling more capable.

Start small and don't put too many things on your agenda right away. You can build that up as you start feeling more confident.
