Welcome to mamampedia!!!
You need to talk with your doctor and let him/her know what is going on.
You are VERY young and have 2 kids under 2??? That in and of itself would lead to no sexual desire, hair falling out and mood swings.
You NEED to talk with your doctor. You need to have a check up. Is it possible you have postpartum depression? I don't know. But strangers on the internet can give you THEIR experiences but a DOCTOR can examine you and run blood tests...so GO TO THE DOCTOR!!!
