Post partum depression

I have PPD. I haven’t went in for it because I have no motivation right now. How will they help me? I’ll always have my baby with me, and he’s the one who gives me PPD. I feel guilty for feeling this way, because he hasn’t done anything wrong. He’s so innocent. I do not think about harming and neglecting my baby at all nor myself. I do however, think about just leaving. Leaving everything behind & doing what I actually want to do... and that’s to move to a new place, go back to college for nursing & work. Party. Flirt with guys. I’m 20 years old, that is what I should be doing. Not raising a child, it’s not what I wanted so soon. I didn’t even get to live my life, I was barely starting.
