Luckily for you vegetarians do not eat fish. You would more fit into a vegan meals since you cannot eat eggs nor milk.
I posted in the sources section, websites for recipes and how much you should try to eat from each food group.
Vegetarians do not eat fish. Fish are just as equally important as all other animals.People that eat fish but not other animals just wants to feel cool and want to give themselves a label.
I haven't ate fish in over 20 years.
if you do not feel well when you eat it then that should be a good enough way to stop eating fish or chicken. Another easy way is to stop buying it,
also add veggie chicken to your diet, since you like the taste of chicken but without the animal being killed
