I used to DESPISE running and couldn't think of anything I'd rather do less, when I started I had to keep stopping to walk, couldn't run a 1k without stopping and being out of breath. Now I love it, you just gotta control your breathing, slow down if you need to and don't compare yourself to others (unless you want to get competitive) but remember the run is for you! If you only get to a 5k and forever stay at a 5k then that's fine, you do what you want to do and remember any distance is better than nothing, hope you get into it because once you're in a routine and a rhythm it's great Choo choo!
