Injury ... and patience

This week, I've injured my knee, so didn't do much exercise. It has been a trying week... I've felt very impatient - impatient because it seems like I've been going in the right direction, but again now taking a step back because of the knee pain. Even though, my trainer assured me that knee pain will heal soon enough, it still felt like it I'm stuck - and then started thinking why did I get myself into this state in the first place. How did I really let my body get into this state?! My trainer replied that injury is part of the fitness process, and is to be expected. It cannot be all ups, it has to be an up and down journey. Also, I am travelling to the US for 2 months. And it feels like I might lose the momentum that I've built. And then, how long would it take to get back on track? All these thoughts has brought me to a really negative state....

During the training session, we started with a meditation first. - Focus on breathing thru the stomach. Watch the breathing.  Think of your guru and god, and set intentions - to lose weight, get fit and go on the peace path - and help people. The meditation felt good. Already it seemed like some of the negativity dropped. Thoughts are just thoughts, they should not be given importance. Esp negative thoughts. If there is a thought, then write it down - check if it is inline with the goal, if it helps in any way - if no - then just tear the paper with the thought and throw it away - that  make the thought go away.
Why do we build up on negative non productive thoughts? That does not affect anyone else - no one even knows that we're depressed. But we affect ourselves. And this negative cycle builds up the cortisol - the sugar in the liver is sent to the blood stream and all the organs. This sugar is rejected by the organs, and then gets stored as fat. So the stress and negativity just leads to more fat being stored. So it is important to realize what we think - and if it helps in any way. Realize that the thought is not leading anywhere and only causing negativity, so then write it down and tear that up. This action helps get rid of the thought.
After this we did some stretching and exercises to help the knee recover, and also the sciatic pain. Both reduced a lot - Almost gone after the session.
Mental state was much better after the session. Felt much more relaxed and did actually do the tearing up exercise for a few thoughts. It did help! Felt happier.
