There was a time when I was in school and I was very confident. Had a group of friends and had alot of fun. Talked with most of the people in my class>tried to talk with them. Didnt give a fuck what people thought and ended up doing whatever the fuck I liked wheter it was weird,cringey,annoying whatever( I didnt realise my behaviour was like that at the time). Those were amazing times, and I had tons of fun .But I also did do my best to fit in (or thought I was doing so at the time). However at the end of the year I got to know that i was the most hated kid.

The next few years I tried avoid doing what I did previously, became quiet and being a 'nice guy'. Comfidence dropped. Was only comfortable with a small group of friends. Didnt work out and eventually after school ended (3-4 years later) realised people still disliked me and graduated with 0 friends. ( some acquaintances)

Now I am trying to move on and going to a uni, and I dont want the same shit to happen again. I have disciplined myself a bit. Go to the gym 3 days/ week, do some work etc.,

Need some advice so I dont fuck my life further
