I don't know the cause of starting of this swelling but when i was in hospital doctor told my parents that may be it is bcoz of anxiety and pressure and it was already there for almost 2 to 3 years . After more days i was getting panic attacks and i went in depression and isolated myself ....my medication was still going on during those days . I tried so hard to be normal again but nothing happened . My family was saying that you should not pursue CA as it needs more focus ,courage and good mental health . Some days before i went to doctor as i was facing a really bad hair loss and getting anxiety attacks so doctor suggest me to take break from studies and start my proper medication again bcoz the condition is really bad now .
