How can I express myself to my father that I don't seek ordinary job and  I'm not miserable at the moment because of couldn't find the most suitable job for me?

I would also advise to get started on your career path, even if it's not the perfect job, as it will provide you a kickstart on the way to your ideal job. For many people, it takes years to create to a fully fulfilling career, and it almost always starts with a 'survival job' that can bring you closer to your ideal. Your father sounds like he may be poorly reacting to his concern for your well-being and self-sufficiency. The best way to shut him up is to prove him wrong and get started on reaching your goals!

Sometimes parents have no idea how hard it is to find a suitable job.   Ask your dad to help you find a job through friends and family.  I suggest finding a less suitable until you find your ideal job. We all been there everyone has to start some where.  I am sorry your dad is harsh calling you useless, but sitting at home all day is not trying to find a job.  If you are searching for jobs online and only online is not enough, you should be going out for at least  two hours a day to search for signs like "help wanted" because not every job is listed online.  Also meet up with friends or family word of mouth can also help you find a job.  And search for places where you can volunteer for couple of hours a day, it will look good on your resume and you will meet new people, see where this will take you.

WHo is feeding you, clothing you and seeing you have a roof over you head. My friend, he OWNS you.  Get used to it or get out and do whatever you have to to live on your own.  And "on your own" may mean sharing too little room with too many friends. Its called growing up.  Everyone has to do it sooner or later.

This can be difficult. Many 'jobs' don't pay enough to live on independently, which can be hard to convey to others who care, but just see your 'not working' as a problem. You DO need to make strides in solidifying a career path (whether that's through training, an internship, volunteering or whatever). As long as you are actively (and in some way visibly) working towards a satisfactory job, your father, while still worrying about you, may come to realize that you WILL get that job, but you will have to work for it and it may take time. Good luck!
