How school almost ruined my socical life..

Ok, so this is how school made me loose all my friends..
When I first started in high school I had ALOT of pressure on my shoulders from my parents, school and people around me. I have never been a top grade student, actually I hated school so bad that all my grades where close to F..

But when I started high school I turned my mindset around. My grades kept getting better and better, after the first semester my grades had gone from close to F to almost straight A's During this process I pushed away one friend after the other. All my time went to school, homework and preparing for the next day/week of classes. This is what i had to do to be able to get the grades my family expected from me.

The second semester I kept my hard work up and finished the school year with close to straight A's. I got into the school I wanted (yes it required top grades). But in the middle of the first semester i realised that i had pushed every friend that I had. I tried connecting with them multiple times but they wasn't interested at all. When i finished my schoolyear and moved back home I went to a old friend and we hung out for a day, and then the next day and the day after. And through this one old friend I met a new person all the time. Later on I figured that the reason why I couldn't reconnect with all my old friends was because the way i approached them was wrong I had lost my social abilities and that just because i focused only at school
