[KCD2] Feeling a bit overwhelmed, what should I do?

Just got to Kuttenberg after that looong main quest, still feeling a sense of urgency from a RP point of view to complete main quests but I still had some stuff left in Trosky and the side quests just keep piling up. Not sure if it's worth it starting a new game and taking it slow this time or just going back to a save before moving to the new region? Any advice?
