I have not felt myself for a while now. I felt different after an incident with my friend, where after a day where I would not speak to her, was pushed away by her when I did not hug her after she had put her arms round me.
I can't focus like I used to or interact with people as I was once able to and am affected in other ways also.
What do you feel this may be caused by and what would you recommend I do?
I don't have enough information to know what your experience might mean, or what may cause it. I would recommend that you meet with a mental health professional.
