Glottal fry is trendy?

I am trying to get closer to a diagnosis of what the problem is with my voice. I have noticed that when I speak there is a kind of creak or rough sound or croak in my voice particularly at the end of phrases. Having done a bit of googling I have found a name for this, it is called glottal fry. Glottal fry happens when your vocal folds are not vibrating properly and let through air which creates a kind of croaking sound. I didn’t realise that this has become a bit fashionable and that quite a few celebrities particularly female pop singers such as Katy Perry seem to be deliberately speaking with some vocal fry. There is a trick you can do to reduce the amount of vocal fry that you make. What you need to do is raise the tone of your voice a bit at the end of a sentence or phrase. There seems to be contradictory ideas about whether glottal fry is bad for your voice or not. Some websites claim that it is harmful whereas others say that it is simply a habit that your voice has got into. My main issue with my voice isn’t really the vocal or glottal fry, though this is a bit irritating and uncomfortable, it is more that I lose projection in my voice and find it difficult to communicate in noisy environments. Most of the environments where you are interacting with people tend to be noisy environment with a its being in a restaurant, a bar in a noisy workplace on the street where there is traffic noise so it is quite restricting if you find it difficult to speak when there is noise in the background. I guess that the problem with the glottal fry and loss of projection must be connected because in both cases the vocal folds are probably not meeting properly.
I have been given various diagnoses including muscle tension dysphonia but then other ENT specialists have said that I don’t have muscle tension dysphonia, others have said that the problem may be caused by what is known as silent reflux, i.e. reflux which you don’t really feel but which can affect the functioning of your larynx. One of the recommended treatments for this is to take proton pump inhibitors and Gaviscon. However, when I have googled there the doesn’t seem to be much evidence that proton pump inhibitors are helpful for this kind of reflux.
