Lost my sense of “self”

Since having my son, almost 9 years ago, I’ve slowly lost all sense of who I am or was, before being “mom”. Once a social butterfly, now friendless. The thought of someone asking me what I like to do for fun makes me cringe, because I literally don’t know. I can be in a room full of people yet I feel alone (or would rather be alone). I’ve been to doctors, therapist, counseling, you name it. I’m terrified that I will never go back to my normal self, nothing seems to help. Please tell me I’m not the only one 😔
