Thank you very much for all these responses. It is very helpful, I have no talked about this with anyone yet.
I'm bored, it is true, my life looks like daily routine, wake up every single day in the same time, go to the same office with the same people etc. but I feel I have no energy to start new things. I was trying to pick something new up like courses, new language, even new physical activity but I hadn't enough patience, energy and willingness to learn it or pursuit to achieve. I feel like this pointless, this is going nowhere and I need to leave and waste my time with stupid things like watching tv or playing computer again because it is comfortable. I cannot enjoy my life any more. I think is it not typical boredom as it I have been having this feeling for 3 years...
