PvT Help

Hello everyone im fairly new to sc2 ive only been playing for about 4 months now. I recently got promoted to gold league and I'm having a bit of trouble against terran. In general I'm pretty heavy with the stalkers. As a result every PvT game i play my oppenent has 50-100% marauders. I've tried using more zealots but then the mauraders kite me with stim and shells. Ive tried high templar, collossus, and void rays but nothing seams to help
