>>1 I've been dealing with the almost exact same issues for a while. I feared being branded as an attention seeker as well, so like you I hadn't opened up to anyone. I put up a happy pretense but I kept getting worse and eventually my mind was affixed to a dark and scary mindset. My friends and family who were initially completely oblivious now started to see the cracks in my happy act and started to ask me whether I'm okay or not, I didn't want them to worry and I knew that I couldn't keep going like this, so I went to a doctor who then referred me to a psychologist. One of the biggest factors in my choice to seek medical help is the fact the without your explicit consent everything is confidential, so it was up to me to or not to tell my friends and family. However I wish I had the good sense to go get help earlier since my issues has had an adverse effect on my life, work and relationships.
It seems to me that you are seeking help and not seeking attention. And from my experience, I'd strongly advise you to go to a psychologist or a doctor for help and it's up to you if you want to tell anyone.
