It is all in the mentality

I’m in week 10 of my first pregnancy and the morning sickness is really terrible. I get terrible headaches, nausea all day. Loss of appetite. I am only able to eat one small meal a day. Insomnia due to nausea at night until early morning. I can’t stand for so long without feeling like i am going to pass out. My husband is not being supportive at all. He says it is all in the mentality. It is so stressful i’ve not experience a single bit of joy. Just anxiety from thinking if i am a good mother will i be able to carry this baby well.
