Working Moms! Tips on returning to work?

I've been in tears the past few days after my husband and I decided I needed to go back to work soon. Possibly next week. I'm not angry, I'm happy to contribute to our long term goals of paying off debt and buying a house. We are just barely getting by without my income. Our little guy was a big surprise and we weren't yet equipped financially. He is about to be 10 weeks old. I know some moms go back even sooner than that. But my heart is breaking! I will be gone all day and by the time I pick him up, its his witching hour and then bedtime soon after. I will hardly be spending any time with him during the week. Will he become indifferent to having me around and get used to me just not being there? I also hate the idea of not being in control of recognizing his needs and meeting them. I know him and his cues so well. It feels so wrong leaving him, but I've already tried finding ways to stay home with him the past month and it hasn't been working. I also keeping wondering if I have been a good enough mama the past 2 months to make him love me enough. 😭 I'd appreciate any reassurance or advice from moms that have gone through this before! Thanks!
