You're 25. Life as an adult is just starting, so I wouldn't worry too much about feeling like you're a failure because you haven't done x or why by the time you're z.
Cutting all your comforts and promising yourself you'll get a job by the end of the month is probably going to stress you out even more and be counter productive, baby steps are the key.
You need to work out what direction you want your life to go in - straight into a job? Qualifications first? Train on the job? Once you've done that you can start the baby steps process to getting there. Set yourself a realistic target such as getting a local newspaper to job hunt, do your CV or get some prospectuses by the end of the week and go from there
Hope you get it sorted mate.
