The first paragraph talks about vomiting a little bit but it's not graphic or descriptive; I thought it is only fair to warn you because of your phobia of vomiting
I also have a fear of vomiting (I didn't know what it was called; thank you for that information
) but I think it is an extension of a fear of choking. I hate having coughs for that precise reason. I was a very healthy child and consequently didn't vomit once from the age of about 7 to the age of 16. It got to the point where I'd forgotten what it felt like to be sick and what it felt like just before that so the phobia developed. I used to get a swooping feeling in my stomach if someone even talked about vomiting or if I saw it and I would turn of TV programmes if there was any vomiting in them. That has got steadily better but I still get unreasonably anxious if I know somebody near me is ill.
The choking/coughing element of it started in year 4 when I inhaled my own mucus (sorry for the details but I think it's necessary to understand what I'm talking about) and almost choked on it when I had a cold. My teacher said 'I thought you were dying', which is not a good thing to say to a child. Then it happened again in year 7 on my second day of secondary school. I had a cough for months after that and went through a lot of problems with school attendance. My teachers thought I was emotionally unhinged but I was only quiet and scared at school.
In year 8 I too stopped eating properly for no apparent reason. I just felt like I couldn't swallow properly (fear of choking again; too aware) and I lost a lot of weight. The doctor knew it wasn't a standard eating disorder because I had a positive attitude towards food in general. I was used to get anxious leading up to meal times (which is probably why I couldn't swallow). The doctor did full blood tests and it turned out that I have Gilbert's Syndrome; they used this to explain my problems while simultaneously saying that it had no symptoms. Make of that what you will. I was referred to the outpatients department at our hospital and had my weight and height monitered until I was 16 but the eating problem had gone by the time I was in year 9 and I've never had any problems with eating since then. In fact I've become even more normal in my eating habits that I was before it all went wrong and I enjoy food immensely now.
I've had daily nausea (no vomiting) since the age of about 13 (I always thought it was due to Gilbert's Syndrome but I'm not so sure anymore). As you can imagine a fear of vomiting coupled with daily nausea is not a fun combination. While I've got used to regular nausea and can function in spite of it, I get anxious when I'm put in situations where you could construed to be 'trapped'. I get nervous on trains/in the cinema/at the dentist/at the hairdressers/in restaurants but I always feel better once I get there. I've learnt to overcome that feeling.
The strange thing is any anxiety that I feel is always related to how I feel and never to do with the task in hand. I get nervous about taking exams because I don't want to feel ill in the middle of one and not because I'm worried about the actual exam. I tend to work hard so I don't get as nervous about the actual questions and work.
I've never had depression or panic attacks like you and I've always been in mainstream school. There was a very good special needs department at my school who helped me in year 7.
I was handling the nausea well as years of it had allowed me to get used to it but two years ago I started getting vestibular dizziness symptoms (not the room spinning kind but the kind that you feel within your skull, if that makes sense). I've been through some hospital departments to try and find a solution (ENT, neurology). My MRI was completely normal apart from one tiny looped vein but that's not the cause of my dizziness. I'm currently pursuing the hormone imbalance route.
