Feeling stress can be so draining. May God grant you peace of heart.
And don't worry too much about the mistakes you may have made in the past. Remember, we're all imperfect, and we all need God's help. So God came to help us, to reach out His hand and lift us up! Because He loves us, no questions asked, totally and unconditionally. Mistakes happen, and God is ready to forgive when we're ready to turn back to Him!
No one does His will perfectly, but we can try to get a little closer to Him everyday, patiently, bit by bit.
Why do you think you're feeling this stress? Is it something at home? At school? If you figure out what's causing the stress, you can then take steps to lessen it.
It can be hard to love people when other stresses are bothering us. Different people find different strategies work. Some people try to find quiet time, alone, to wait for the stress to go away. That way, when they're back with their family, they're in a better mood.
You may want to talk with your family, explain to them that you're under a lot of stress, and apologize for taking it out on them in the past. Seeking forgiveness is a great way to draw closer to people, and to God. And this can open the door for your family to help you with your stress, so you can all work together to create a more peaceful environment at home.
Maybe you can all set aside special family time that's totally stress-free: you can play games together, have dinner as a family, talk about your day, say evening prayers together. That way, you're all ending your days together, in a loving and peaceful way, and keeping your hearts centered on Christ.
May God always bless you and your family!
