Prayer for the Strength and the Presence of the Lord

Sometimes I want to give up on life because I am so tired of the problems in life. Sometimes, I think that God is not in my life because he just let me suffer like this. How long will I endure?
Please, the Lord will guide me to the right path, give me the wisdom and knowledge to know him more and help me carry my burden. I know that the Lord is always there for us. Pray that I can feel the presence of the Lord in my life.
Thank you so much for all your prayers.
