Thanks for your question,
I'm sorry that you've been advised that this website is a scam. There are certainly many qualified professionals here with proven track records of helping people out. While I certainly understand your frustration in being unable to overcome your phobia, I do think it is important to point out that the most proven method for conquering any phobia is a combination of CBT and exposure therapy. All phobias, no matter how complex, are generally treated similarly because they all stem from irrational fears. Because of that, your phobia may be more complex due to the severity and length of time you've been suffering from it, but the solution remains the same.
Generally the problem in exposure therapy is that people give up on it long before it works because it is a long and difficult process. However, if you are looking for proven methodologies, this is it. If you think about the basic concept of overcoming your fears, it logically makes sense, and people who stick to it have success. While the quality of your therapist may certainly help, exposure therapy is something that you must also do on your own on a regular basis. Unless you are consistently working on this problem in your own time and doing your exposures, then there's a good chance that you'll continue to shuffle through therapists, since the bulk of the work depends on yourself.
I do understand your frustration with finding a good therapist. That can obviously make a big difference. However, since all phobias similarly, I would recommend you pursue a therapist who has experience using the most proven methodologies for phobias, which is CBT and exposure therapy. I definitely wish you the best with all of this, and if there is anything else I can do to help just let me know.
