Hello @Gonewiththemoon
I am a psychologist and a hypnotherapist and have worked with people with emetophobia many times. It sounds like you have reached a point where you just can't go on like this as your phobia is affecting so many aspects of your life. You can make a change, and it is good that you have found hypnotherapy helpful in the past, and there is a way to get the benefits at home by using this site, it is so good, I recommend it to anyone that is struggling with issues especially anxiety and fears and phobias.

Maybe start with this one, as it is not directly tackling the phobia but anxiety in general. If you were coming to see me for sessions I would have a session or two around managing intrusive thoughts and anxiety first, and use the concepts in this audio all the time very successfully:

Listen daily for a week or two, and practice the concepts whenever the thoughts begin to intrude. If you find it helpful, and are not ready to do the phobia work yet, there are lots of other really lovely, calming audios on the site that will help.
This one will tackle the phobia, and again listen to this as often as you need to, but maybe when you are feeling calmer, and not when you are in crisis. It is exposure therapy of sorts, it takes you to a relaxed state and then has you work through memories and feelings around vomiting in a calm and controlled state.

The site has many really helpful self-hypnosis audios that really do work. I use them on myself!!
Good luck, you can do this. Take it one step at a time and be kind to yourself. This anxiety is so ingrained in you, has been there for so long, it is almost part of your personality now. It's like a toxic relationship, it can be hard to imagine life without it, but it is possible.
