confused caregiver

ok so here goes nothing...i've been doing this for a while now, taking care of someone in their home and sometimes we end up crossing lines into these intense moments where i feel like the one making decisions. it's not about being a parent or anything specific.... just that sense of responsibility and authority feels good somehow. but then i start thinking about what it means to be so close to someone else’s life like this and worry if there's something wrong with me for enjoying it so much.....anyone else ever feel weird about this? is it normal to get off on being the one in charge or am i just a freak?
