I feel horrible

But sometimes I just sit and let my 3 month old cry. I’ve changed her, I’ve fed her, I’ve burped her and she won’t stop so I just put her in her crib and leave the room for >10 min😓 I just can’t take it sometimes. I’m a teen mom and her dad lives 2 states away. I have no help and I’m extremely depressed. Should I stop doing this or could it actually be good for us?

For those saying I need to speak to my doctor about PPD I have and I’m on antidepressants
