I have low self esteem and depression after I gave birth and found out my husband left us for another woman. Is there anything I can do to treat this?

Depression. I'm so sorry to hear about your situation. That is very distressing to you. Also, many ladies suffer from postpartum depression. The combination of the emotional shock and your postpartum state can make a person very depressed. See a doctor as soon as possible to discuss these symptoms. Remember that your life is precious. Call 1-800-suicide if hopeless or thinking of harming yourself or others.
