Type 1. I need a diet plan. Help

Right now my diet is not good but okay... I don't have a pump so inject insulin. Right now my carb to insulin ratio is 10|1(unit) But it doesn't matter. I don't know what Is going on. My body can't handle the carbs I'm eating... Maybe 70 carbs per meal is average. But 2 hours later my blood sugar is in the 200s... What do I do?
