from your picture it looks like you may have a small child running around along with 2 others.
First off congrats on the children and second you are going to be FINE!
Have you ever heard of Post Partrom Depression?
Did you ever have that after your children's births?
Its most common in women and can easily be reversed with the right medication.
As for your out bursts... you have to remember YOU HAVE 3 CHILDREN mommy! And a boyfriend!
Raising 1 child can be stressful for a person.
And our men can do more harm than good sometimes.
My suggestion is you go see another doctor who can better understand your concern.
If you are having any feelings of dispair than they need to be addressed.
You shouldnt have to suffer alone. There are soo many people out there just like you.
If you can find someone to watch your children, then schedule an appointment with a therapist in your area. They will evaulate you and refer you to the proper doctor.
Sometimes just talking to a person, a stranger even will help that weight be lifted off your shoulders.
