2 months ago my marriage proposal for cancelled just before engagement for the 2 time and it was my mistake. After that I was always lost in thoughts about how guilty and worthless I am and could not concentrate on anything. During this I lost 3 snd halft kilos within a week. The following month I used feel very sad first halft of the day and get negative thoughts often. Currently all those are less intense. However I have lost interest in doing anything and even I feel that can't manage a relationship in future and feelscared of any social situations. Feels like happiness is fine from my life. Healthwise I mean okay but from time to time I am getting shoulder pain. I just want to know what is wrong. I just tend to avoid people apart from those who are very close.
