Well fuck, Diego, I didn't know there was a baby involved.
With the thoughts and feelings, let yourself think and feel them. There's nothing wrong with having emotions, as much as they can be uncomfortable at times.
As for how to help Lila, you should start with asking her what kind of help she needs. Financially, emotionally, and so on. And if she says she doesn't want help, then you should respect that, but still make the offer and be there for her if she changes her mind. Be supportive, but let her lead that. Communicate and all that shit.
