Chronic nausea is ruining my life

hello all, im just writing for some advice or just even see if im not the only one suffering like this. ive had nausea for over 4 years now, when it started it wasnt too bad, i could ignore it but still tried to see my g.p about it, it took me 4 months of constant contacting different g.ps about the problem to get my first anti sickness meds which was procloperazine. over the years the nausea has gotten worse, and im still getting nowhere with my g.ps. ive tired many different nausea meds(currently on cyclazine) they kind of work, just enough so i wouldnt actually throw up. in the last few months ive gotten to the point that i just lay in bed all day when im not in work, i always cancel plans with friends and never go out really, cant exercise either as the nausea increases with physical stuff, and im even worried that ill lose my job now because they are not happy with me having taken so much sick leave in the last year(i did have an operation to remove 3 ovarian cysts which i thought was the problem to my nausea because the biggest one i has was 25cmx18cm but it didnt change anything). im currently waiting to have a meeting in my work because of this. since my operation my problems have gotten gradually worse till now. i also have worsened menstrual problems too which is making is also i think contributing to my bad fatigue and also makes me get light-headed sometimes when im on. currently ive had a lot of tests done but none show anything wrong, ive had a ct scan of my abdomen and head(due to migraines that i had last year) several ultrasound scans of abdomen and one on my throat ive had a camera just into my throat ive had that bacteria test on my stomach countless blood tests. im currently on the waiting list for a camera to my stomach and to see my gyni again, ive also been booked for another ultra scan on my abdomen and liver. the reason they are looking at my liver now is, i had my covid injections in the begining of the year and got an infection after both so had to have antibiotics, at the time i was also having migraines as a side effect of them too, so i was taking ibroprofen, i think due to these meds, my liver function levels got up to 68, i got another test done last week and its come down to 51 so they still arent fully happy with those levels. the doctor said they dont know when ill actually get my appointments in the hospital because there are such long waiting lists now, but idk how much long i can keep going like this. my occupational health nurse from work called the other day to assess me and i ended up breaking down with her on the phone, and so shes refered me to speak with a counselor which i doubt will help tbh. sorry this is quite the long one but i thought id try and get in as much info as i can. love to all 💙
