Hi Toula,
Are you still in Greece? One of my childhood best friends recently moved back. She is about 200 kilometers from Athens, and she struggled to find work. The quickest answer is: nothing is wrong with you. You are currently in Greece.
However, more personally, you are currently experiencing your Saturn return, in which transiting Saturn returns to the same sign and degree as it was when you were born. Saturn is at about 3 degrees Sagittarius, and is making an exact conjunction to Mars right now, and will make an exact conjunction to Saturn soon. Both of these planets are in your 6th house, the house of jobs (not career or vocation). This is the house that shows where you do labor and how you do it.
What does all of this mean, in plain language? From looking at your chart, I see you as a person who is less interested in making money and dealing with the material world and more with the ideas of thought and philosophy. Travel may be of great interest to you, though I don't see you as someone willing or compelled to permanently relocate in order to find work. You may be interested in working in travel, but not necessarily in hospitality. How good is your English? Would you consider working on a cruise boat? Cruise lines hire people from all over the globe, and while the work can be hard, there is long vacations in between cruises, and you get to be on the water, and you get to travel. People may naturally find you hospitable, even if they wonder if you are reliable. You will have to prove them wrong, and this will require patience on your part.
However, finding a job you feel suited for and one you can stay in for the long haul is going to be difficult for you. This is largely because you may depend on others close to you to help you with work, and in a down economy, this may not be possible.
One solution I will give you is to make your own job. Do you have a business-minded friend you can help out, possibly partner with? Is there some sort of service you can offer on the Internet? To work and to be of service is something you take seriously, though you may be prone to losing your momentum once you are in a job that you feel is too stifling or gives you no room to move about. A desk job on someone else's schedule wouldn't work for you in the long run, as you need freedom to make decisions, come up with new ideas, and generate enthusiasm. You may be very good at helping to promote something. In a small business, everyone who works in the business helps to promote it. However, your tendency may be to find someone who wants to reign in your enthusiasm. As you get older, you will be more able to find someone who is less interested in the mere labor you provide and more interested in your brilliant ideas to increase business. However, be careful about who you partner or work closely with, as you may think they are the best person ever at first, but become disappointed later when you find out that this isn't the case.
Since you are unemployed, take this time to look around and see if there is something you become enthused about, that you think you could sell and promote to people. Right now, it may simply be your labor. There are places online that you could take freelance jobs (which may be good for you in the short-term, and help you build a solid reputation as a hard worker) doing translations, promotions, etc. There is little investment other than time required in order to go out and get the jobs.
Take heart, and take care of yourself and your health. Right now, you may feel very stuck and hopeless. Take this time to examine your sense of purpose, and what you want to offer the world to make it a better place. A normal job in someone else's company, doing whatever they tell you to do, is probably not for you, and I think that employers may sense that about you. The good news is that the world is changing, slowly, toward self-employment, which I think would be a better option for you. You can work hard and intensely for something that you really feel is a good idea and really changes the world for the better. This is more important to having a good career than being able to merely follow someone else's orders.
