Can anyone help with Sleep Phobia?

Hi all.

I am a 45 year old female, and in short, I have what's called Somniphobia - which is basically a fear of falling asleep - and it's something that started immediately after a troubling event I had as I was trying to fall asleep nearly 16 years ago and something that I've been dealing with ever since.

I sleep on the sofa and have the TV on every night, and have done this for many years. I never sleep in my bed or without the TV. These are the tools that I've come to use as my only defence against the fear of going to sleep in a bed and in silence like I did before, and like most people do without a second thought. But even with these crutches, I still have a relationship with sleep that is fearful and not normal...

I have come to the point where I am tired of dealing with this issue and I am ready to find a way to deal with it, but I am struggling to find any information online about what the best way to tackle this issue is, or what an effective treatment might be...

So I am looking for any information from anyone who has or is suffering from the same thing, and hopefully, and help from anyone who has found any treatment or therapy that worked for them in managing or overcoming this specific type of phobia.

Thanks for reading and I welcome any information or help that anyone can give me. x
