Where to begin

let's do it  3, 2, 1....

When most of my final university exams ended, I realized, I wasted a whole year of my life, going to school like I did since I was six. I thought university would be different, would give me much more freedom than highschool ever did, would generally be more evolving and entertaining,let me develop my talents at a faster rate.To my surprise,it was exactly the opposite,It felt just like high school,same level of injustice,teachers who got bored of their lives long while ago,subjects that aren't really useful,or relevant in my career,at least not in early stages of evolving.I study engineering,industrial design to be precise,or should I say I studied? Because I seriously consider quitting...I really feel like I was much happier with life&interested in the world exactly a year ago.SO, I am taking a step out of this pathetic system,not present my self for the upcoming exams,and I decided this summer I will cycle the north coast of Mediterranean sea,just by myself,since no friends of mine wanted to join me(that's also disappointing...I met no interesting people).I need an adventure,exploration,and meet random people in random places.A break from continuous routine of meaningless things.
As a proper unorganized teenager I havent planned this VERY well,just the essentials,I bought most of the equipment(bags for the bike,some shirts,new pedals...) I don't want any weight on my back,since I have planned to do around 100km per day,

as you can see google says there is no way to go on bicycle ;-) let me check it

I dont have a tent, just a sleeping bag and waterproof 3x5m sheet of material (to cover my bike&myslef up?).I used to cycle 38km each way to my campus with a backpack(3-4kg) so I considered 100km wouldn't be a problem,but all can be modified along the trip,I train on a daily basis,so cardio prep isnt really necessary. Today I downloaded most of the offline maps for HereWeGo(free&great navigation app for Android) it has cycling routes,so that will be very helpfull.
About the places I will be sleeping in,a member of my family found this page who has almost all of the caravan,paking,resting places in all europe, www.areasac.es,very helpfull,and offers files with the maps for free download(which I havent done yet).So far I planned all the way through Spain(starting in Huelva),France,gonna stop at Monaco,Italy,Slovenia and Croatia.My family comes from Poland and thats my final destination,but Im still unclear wheter I will go through Austria,Hungary,Czech Republic,or Slovakia....But I will be starting my trip on 1st of july,so I have pleny(actually not) of time to finish polishing the details.
I'll try to upload a rough approximation of my route tomorrow,to add some sense to this
