She's in college so is either doing school work or too drained from doing the work that she doesn't have the energy to hold a conversation and I know logically that's the case but I've caught myself thinking she's abandoning me and that she's a horrible person. I know both of those things aren't true but I still can't stop feeling like they are. I really don't know how to handle this so any advice is much appreciated because I really don't want to lose her
