Alex, prayers you have here, and I'm sure more to come. Personally, it helps me to know generally how old you are, so I know what phase of life you are in. Are you a teenager with struggles that come with that phase of life? A young adult? etc. If you prefer to keep it there and just want prayers, that's fine.
If you're tired of sinning (and we all sin), that's terrific, because you recognize the conviction of the Holy Spirit showing you areas that are causing this separation. Too many people are oblivious to it. Our God loves you and is wanting you to put your burdens on him.
I like to look at the psalms, and put things in perspective. David and Solomon were pillars of faith. Yet, they sinned, and psalm after psalm shows us how many times they cried out to God asking where He was. Clearly, they felt much of what we do sometimes. But, the Lord never forgot them, and He has not forgotten you. And meditate on this scripture from Matthew 11.
28"Come to me, all you who are weary and burdened, and I will give you rest. 29Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. 30For my yoke is easy and my burden is light."
Spend quite time alone with those verses. Quietly read though Psalms. If you have a home church and feel at ease with the pastor, arrange to talk with him. If you don't have a church, or your pastor isn't someone who gives you that comfort, ask someone who might suggest an inviting pastor or church.
Be still and know that He is God. He will make His presence known,
"And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus." Philippians 4:7
