Oh my!! I am so sorry to hear about all that has happened to your family!! My niece can't stand enclosed spaces and can't do an MRI because of that.. I just prayed and hung on... it was 45 minutes. along time if you can't stand being in there..you may have other things that are causing the nausea..just being sick all the time is extremely stressful..I stress all day about what to eat.. and people don't understand.. but if I eat the wrong thing.. bad results.. your feeling are valid.. don't let the doctors tell you that "it's just stress"or anxiety..I take Zofran 8 mg disolving and promethazine currently as needed for nausea..(along with other stomach meds..) you can find scriptures to help you by googling and they will come up..standing with you in faith for insight ..and wisdom..here's one for those doctors.. Proverbs 3;4 So thou find favor and good understanding in the sight of God and man..sometimes the doctors are the problem...Good bless you precious lady!!
