We don't walk by feelings. We walk by faith. You're not weak in faith. Just learn to trust God more and the way you can do that is to read your Bible and fellowship with him. Reading the Bible grows our faith as we read about how God helped His people and even sinners, who came to Him for help. You don't have to feel that God is listening, in order to know that in His Word, He always keeps his promises. He said He is always listening, and He is. He always keeps His promises, so don't allow Satan to make you think that God is not hearing you. And also don't let him tell you that you're too weak in faith because that's what he tries to do to make us feel unworthy and depressed. He wants us to give up talking to God. He doesn't like that at all. He always hears us. Only trust Him. God answers in His time, when He knows the timing is just right, and in your best interest. Just keep on loving God and keeping the faith. God is no liar. He is trustworthy. Continue to read your Bible as much as you can and having fellowship with God through prayer. And you don't have to be on your knees to talk to God. He loves to fellowship with us and you can talk to him any place you are at, at that moment. Remember that the more you read your Bible and fellowship with the Lord, the more you will grow in faith. It takes time to grow in faith, so don't be hard on yourself. And just speak to God from your heart. No special words have to be spoken. Satan doesn't like it when we're close to the lord. He will tell you that the Lord's not listening or make you believe He's not listening. That's just a devil's lie. Look at the promises of God in the Bible and you will see that.
