Feeling lonely

there was this girl, who was like my best friend since over a decade. Few months back she got promoted in job and same in her attitude and behaviour. Was attached so much to her all these years and same was she. With time, priorities change and experienced in last few months. Once I use to be top priority, but as my rock bottom phase has started she decided to keep me aside until needed. May be I am expecting too much. But what has made happen is I turned too lonely which I never use to be. Sometimes being too close to someone leads to too many expectations and later disappointment. Few time ago had anxiety attacks because of such pain. Now recovering slowly and with time hopeful will be over. Things that I am learning is that one should be busy in himself/herself so well that it doesnot need to seek happiness from others. About anxiety, its just waste of time. Eventually whatever is meant to happen, will definitely happen. No matter how hard you have tried and made efforts or anything else. So its better that start living in today and stay opimistic as much as possible. It will help get over stress and anxiety. What I personally prefer to avoid anxiety is listen to some interesting music never heard before, go out for a walk or drive, have some chocolates, watch some funny things on youtube and do things you always want to do without being hesitant. Hope this helps to all those who are going through hard times. I wish happiness stick to them forever. Stay happy. Stay Blessed.
