Depression

For a while now, I’ve been having symptoms that I thought were normal for some reason... I always need to be in bed if I’m home. I never want to go out and do anything that I would have normally enjoyed. I have no appetite still. I can barely get out of bed for work in the morning. I have severe separation anxiety from my husband and I always feel alone. I told my friend about it and she told me to contact my doctor immediately. I did, and my doctor told me I’m extremely high risk for post partum depression and she put me on Zoloft. She now wants to check me every 2 weeks instead of 4. My anxiety is acting up again. Im worried and nervous now... anyone with similar stories?
