Yes hi there I'm a mom with a now two and a half year old daughter. I suffered really bad with post pardum depression. You said you have a 16 month old is that correct? Have you done any sort of sleep training? He should be able to self soothe by now. Sleep training is so hard listening to them cry but after a few nights it gets so much better. Is there anyone to help you and maybe take turns in shifts so that you can get some sleep? Have you talked to your doctor about PPD? Sometimes symptoms don't show up until a year later. Don't feel like a jerk it's normal to be frustrated. But my anger was a clear sign of my PPD. I'm on medications now and I feel so much better. Read up on sleep training techniques as he is old enough to do it as they need to learn healthy sleep habits and learn to sleep on their own. Feel free to message me if you ever need to talk. Sending hugs your way. It does get better!
