Hi Illumina, I'm sorry that your past experiences with therapists and other professionals have not been helpful, but I am glad that you received the help that you needed.
Unfortunately there not just good ones but bad Therapists as well, despite their education and the Hippocratic oaths they've taken. There are those who are utterly new to their field and then there are others who are presumptuous with their clients and patients.
I can only guess what you've been through with them.
