Frosting melts too quickly in my hands

It doesn't take long for my frosting to melt into a non pipable goo. Does anyone have tips for this? I have to keep putting cake and frosting back in fridge for half an hour and it's making the cake process really slow for me. I'm working in small windows between work, school, life...there has to be a smarter way to bake cakes. Please educate me.
