Post partum depression

I'm 8 1/2 months post partum and since last week have noticed I'm not myself.

- I've been very irritated with little things that wouldn't normally bother me- seems to be getting worse.

- I cant stand my MIL and seeing her (she was too much when she found out I was pregnant and then seeing her weekly since baby has been born is a lot for me- she also likes to make comments about what I should be doing/shouldnt etc. which doesnt help!). Longest stretch I havent seen her is 2 weeks. I actually feel anxious if I have to see her.

- I feel neutral (not happy but not sad)

- I'm not motivated to do anything, I dont want to cook, clean or go anywhere

I am however absolutely in love with my baby!

- I also feel really self conscious of my stomach and I lost a lot of the baby weight!

I havent talked to anybody about this yet but considering contacting my doctor. Do these feelings go away on their own?
