What to do when sick and tired of being sick and tired?? Help please!!

Posting anonymous bc some people may feel I am ungrateful which I'm not I tried to get pregnant for 2 years and multiple iuis. Now I am 9 weeks and I cry everyday. I'm just so tired of being nauseas every minute of the day just gagging constantly and not being able to eat or drink. Idk how women do it I had no idea it would be this hard. I'm constantly dizzy and lightheaded and the nausea just is taking over. My doctor prescribed me diclegis but it's just controlling me vomiting but I still go into gagging fits atleast 5 times a day. Just thinking of food or a restaurant or a certain smell will throw me into one. I can't even take my prenatal vitamins and now I am feeling guilty that something could go wrong with my baby's development. I wasn't prescribed zofran but I had 6 extra from before I was pregnant that I took to feel normal again. I'm just trying to do the best I can and basically survive. I'm just miserable and it's effecting my relationship with my husband. I can't be intimate bc I am so dizzy and nauseas. I'm also snappy bc I feel like I'm dying. I just don't want to resent a baby that's not even born yet although I know it won't be this way once he or she is born. I'm just crying myself to bed. I am at a loss. I have a doctor apt Thursday and I will tell him idk what to do but how did any of you ladies get through it?!
