17 weeks and I'm not sure if I'm just depressed or pregnancy symptoms

Darnesha
Ladies I am really struggling with depression I think... I find myself worrying about every little detail of my life and it's a struggle to get out of bed in the morning and as soon as I get home I want to go straight to bed and sleep until the next day. I have a job in sales that I just started and it's very high paced and stressful and if my numbers fall below a certain percentage I lose my job after three months however I have been during fairly well at. I think the idea of having a baby on the way and not having a job is stressing me out and also child care and all the other things that come with being a new mommy.
I just feel so overwhelmed with life and inherently unhappy and very lethargic... I don't know if I'm suffering from depression or if this is a normal part of pregnancy.... is anyone else going through this? By the way I have a very supportive fiancé that loves me and works very hard...i'm just struggling with showing up for life if you know what I mean?
