Find and visit an eastern orthodox chruch, every sunday and partake in the eucharist. Read church history, eastern orthodox theology and early church fathers' teachings. Christ has left a Church for a reason and you won't be fully in communion with Him if you are going to the watered down versions of God in the protestant or roman catholic churches. It may sound egoistical at first, but as i said, learn about history and theology and you will get to the truth.
Try to pray every morning, every night before bed (get a prayer book) and/or get a praying robe and use it to count the Jesus prayer, which goes like this: "O Lord, Jesus Christ, Son of God, have mercy on me, a sinner.
I would also reccomend to fast atleast every wednesday and friday as well. That is no meat, eggs, dairy products, fish, oils and alchohol. You should also try and abstain from other distractions, like social media, sexual pleasures et cetera (and everything that you think that distance you away from God)
You need to worship God and make him a part of your life or you will come back to worshiping sin. I can tell this from experiance. And remmember that Our Lord gave us a sword, not peace. He did not remove sin and sin will be a part of life until the Final Judgment. But he gave us tools (the holy sacraments, his teachings, the church ect.) to combat sin and to take on a jorrney to get closer to God.
I do not know what you are struggling against specifiaclly, but i hope that you will overcome it. It is possible and you should never give up!
God bless!
