Your body will adjust...it just takes time. But in the meantime you don't want mastitis and being engorged could lead you down that path. I would recommend pumping/expressing just enough for comfort (don't drain the breasts, just enough to relieve any discomfort). There are many uses for EBM- bottle while you run an errand/take a bath/get a pedicure, milk popsicles while teething, use in cereal in a couple months, use for home made baby food in a couple of months, etc.
