Hi G.,
I would like to say take one day at a time. People underestimate the effects of any kind of health changes on the body. Pregnancy can have very profound effects on some women, and if you are unaware of them, you or anyone can feel down, overwhelmed and discouraged. In my opinion, two things that are key during pregnancy and motherhood is faith and family/friends. Sometimes you have to do the opposite of what your feeling to overcome whatever challenge you are dealing with. For example, if you feel discouraged about something, do something fun and encouraging, like do things with family or friends even when you don't feel like it. Not often, but on certain occasions and it will get better with time. Try this in other areas of your life, and you will see a change. Also, if you think you might need professional support, go and get help.
I am telling you this because my children were born two years apart, and I went back to work full-time(teacher) after the birth of each one. It was very hard with my husband working full-time, and not alot of resources for childcare. The finances were in total disarray, so I understand how these challenges can make you feel. I just want you to know that you are not alone, and many families are faced with the same thing, they just seek out the necessary support to help overcome and cope with these kind of issues.
You are in my prayers, and I know you will have a happy, healthy child!
All the Best!
