Hannah,
Don't look at the circumstances surrounding you at this time. Just focus your thoughts back on the Lord Jesus Christ. He knows and understands all the things that are trying to overtake you and discourage you. Remember, one of His names is Man of Sorrows so if there was ever anyone that understands what you are feeling it is HIM.
The Word of God which is alive and which has the power to change not only each of us individually but when spoken out loud can even change our very surroundings urges us to not be anxious about anything.
Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. Philippians 4:6
Just remember nothing is impossible with God and we can do all things through Christ our Lord. We just have to remind ourselves to cast all of our cares upon HIM for He cares so much for us. Just run back to Him and sit at His feet and spend time with Him. He is always waiting with open arms longing to bind up your wounds and heal your broken heart.
Casting all your cares upon Him, for He cares for you. 1 Peter 5:7
Father, We know Your thoughts toward us are of peace and to give us a future and a hope. Your Word promises that no weapon formed against us shall prosper and that the weapons of our warfare are not carnal but mighty through You, Father, to the tearing down of strongholds in our lives. Thank You that You have promised also that if we will resist the devil he will flee from us. We are so thankful that You surround us with Your holy angels and that You let them fight for us in the name of Jesus Christ our Lord. Amen Hallelujah!
