I surprised why your parents did not think to take you to psychiatrist as all are signs of Anxiety depression
.Your depression becomes chronic and it will require long treatment.
As early as possible you consult psychiatrist
so that immediate treatment is started .
You have not to worried it will be completely alright.Few visits and few counselings with psychologist
will give you happiness and new energy to you.
Think positive and leave negative thoughts behind,bright future is waiting for you.
take medicines regularly,medicines will take some time to work but it will change your life
