hang in there. Sometimes it is so hard to go aganst what is expected by others close to you but I assure you, nursing and fostering a close attachment with your darling princess is 100% worth it, for both of you.

Do you have any LLL groups around you? It can really help to connect with some others locally who 'get it.'

I also suggest the book the Womanly Art of Breastfeeding (8th edition) which has an entire chapter devoted to the subject of separations and how to handle them. Pumping, milk storage etc. is covered in another chapter. That is how important the authors felt this specific subject is.
