On the contrary, you yourself have identified three major successes.
All I've done is survive the year. And I'm quite content with that. Why can't you be content with so much more?
Surviving undergrad college semesters is to be expected. If one fails a semester, then either they had entirely too much going on in their lives or they're really not good at this.
Making friends is pretty common for people, and it was out of sheer luck in my case. One cannot be proud of luck.
As for getting accepted at a foreign university, that's a minor success, and common enough with people my age.
Really, if I hadn't accomplished these things, I'd have had a year devoid of accomplishments, which constitutes a failure. Most other people my age do all sorts of good things in a year. Get relationships, get jobs, get excellent grades in challenging courses, master two or three foreign languages... I have nothing to boast of. I'm alternately spinning my wheels in the mud and accomplishing basic tasks that most are expected to accomplish.
When I can manage to drive effectively, get a steady job and relationship, get into better physical shape, become fluent in German and learn another language, overcome my procrastination, and learn how to socialize,
then I will be roughly on par with my peers. Until then I can't help but think I'm lagging far behind in most categories. And that's just to catch up--to be an above-average person in those aspects at least, I'd have to abandon most of my hobbies and continuously and aggressively work on self-improvement for years without letting up.
