I have a neck injury, so normally I would type it out myself, but I'm going to C&P because it's accurate too!
"Saturn Aspecting Mercury: Can give a serious mind, usually much too serious. You may sometimes appear mentally "slow" but that is not due to lack of intelligence. It is because you are cautious and fearful of making a mistake. All Mercury-Saturn contacts deepen the mind. There is little patience for small talk, so if you have this combination, you may appear anti-social. You aren’t, really. You just don’t want to waste time. The stressful aspects tend towards brooding and depression. The cure is (like for most Saturn stress aspects) is to keep busy doing something useful."
So you should find things to keep you busy that you enjoy or that help others, something along those lines. Use that deep mind of yours to do something nice/great/useful like starting a charity or donating your time to volunteer for something worthy, look up inspirational sayings/stories/poems and share them with people you love or care about. There are so many things you could do! Be creative and keep BUSY!
