Life here on earth can at times be difficult. We are in a battle. But persevere. My mother had very deep depression but over time it did pass at least to a point where it's manageable. I struggle with anxiety . It's a difficult road but I know for sure you have a purpose and God will work all together for good for those who love Him. Romans 8:28 Even if you can't feel it.
It is a battle but give it to God- The battle belongs to The Lord. Lord do not let go of this guest that You love deeply.
You are rich in mercy. Jesus loves you still
