+1.. love it. Exercise is good. very focus and enjoying. dont think so much TS. I was in your position last time. As time goes by, you will get used to it. We are living in a very materialistic society but you see here, there are so many nice formers here to guide you and give you advice. Aint this is better than other thing else?
And I dont think your qualification is the main problem and dont compare yourself with other ppl. Why compare? its just showing how immature you are. Right?

Move on. Focus your negative energy to positive energy. It will do you good. Just like me... Challenge yourself with a 5km marathon, then 10km, then half mara and full marathon.. or even take up swimming.. and so on.

Last but not least, take some time off to sit down and have quiet time with God. You are mentally and physically strong but did you realize that you are spiritually weak? Talk to HIM ( no matter what religion you are). Just talk to Him during your quiet time. He might not answer you now but He listens and guide you all the way.


Take care and I know you have potential. Unleash the potential in you! You are another unique person created here on earth. Gud Luck!
