We are bound to face certain circumstances in life but Christ gave us the assurance that He has overcome everything on our behalf. Falling into depression means that the enemy has gained victory over us because that's the kind of state he wants us to be in.
Philippians 4:6 - Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
Instead of worrying we can take our burdens and lay them at the feet of God. It's not what happens that matters but our approach towards it and the steps we take to combat it. Worrying or anxiety can never be a remedy to whatever we are going through, it only makes things worse.
Whereas, we have a Father who is ready to give us a listening ear and life every burdens off our shoulders. It all depends on us. It's how we react to situations that determine how the outcome would be.
