Marta, You're looking outside yourself for too many answers.
Just live life and have experiences with the thought that "I'm going to let life teach me about myself". You don't need more schooling but you do need to put in work at hobbies, a job (you don't need to love the first thing that comes around. There's always another job), personal relationships on all levels (friendly, acquaintance and intimate).
If the above is too ethereal for you, find solace that everyone's lost at 25 (and many are beyond that). You just don't have enough time in to LIFE. Keep doing things until you find the VERY FEW that cause you to find yourself.
