<human>: Give me the gist of the text in a nutshell

So, I've always been more .. big. Not too big, it was always okay for me, but big. However, when I travelled to Fiji last year I was at 100kg and a bit more and I finally decided that I actually want to lose weight to feel more comfortable. 

I was 18 years old back then and still in high school. I tried a lot of things, sports however was never really my thing. I wanted to, but always ended up with injuries here and there. So all I did was to not eat .. changing from Cola to Cola Zero, cutting out sweets and so on. 

Eventually I ended up signing up for a gym. I literally didn't eat anything besides 600g of meat every day .. probably not healthy, but I lost a lot of weight again. I plateaued at around 80kg for several months, but then when I picked up running again (up until now without injuries, up to 20km!) I finally lost weight again. I think the biggest achievement is that I actually don't eat out of boredom/sadness or whatever anymore but only eat to survive .. basically. And I learned to enjoy meals instead of eating them as fast as I can. 

I'm at 65kg right now and I'm always really happy when my fellow students (I go to a university in the Netherlands right now (I'm German)) tell me how they can't actually recognize me on my facebook pictures. 

Unfortunately though, while I lost a lot of weight, I don't really feel more confident. I'm still super shy and put my arms everywhere in front of me or hide where ever so I'm not really exposed. I feel like I still miss lots of opportunities, but it is continuously getting better.

<bot>: Lost about 35kg without really knowing what I'm doing. I just didn't eat a lot until it became a habit to not eat a lot. No special anything. Didn't gain any confidence but still happier than before.
