After having my 1year old son i've been going through a lot of depression, i feel like im stuck because im very confidential and hide my problems, why?

Well, you were : Unstuck enough to share with us. That's a good thing. Some people were brought up not to 'air dirty laundry'. Some families teach 'secrecy'. Whatever, the case is - i encourage you to take the next step toward recovery. This is actually talking to a therapist about your fatigue, hopelessness ; depression. Depression is a treatable condition. You don't need to keep suffering. Take good care of you.
