Hello and Welcome
Sorry to hear that you are having so many problems.
I think the advice from everyone is great nd if you can find a way to get te help you need then get it.
As far as I know you should not have any problems with anyone finding out that you are getting help.
I would think that your parents should be happy if you tell them you are getting help, it is better than seeing you do something bad to yourself from not getting help.
It can only get better not worse, so Please try and find the strength to get the help you need.
Hope you can post here again
Take Care of #1(you)
