This is not going to go easily. You've invited some strongmen into your home and they're not going to want to leave. You're going to have to commit to prayer and fasting to break their grip. And that's just for starters. You need to find a church that isn't afraid of such things, I would say you need to find a charismatic/pentecostal fellowship but keep in mind many of those are fake and your handlers will try to lead you to one. I'll pray the Holy Spirit gifts you with discernment, and that God will send angels to lead you to the right place. You need serious intercession... that is, in a sense, allowing others to place themselves between you and these demons, silencing binding and casting them out in the Name of Jesus in prayer and laying on of hands. You need to also go into deep confessions. When you submit to a demon, you're submitted to that demon until you confess the sin it lead you into and rebuke it. And, like Demi said, even without demonic influence your flesh on it's own is going to crave it's comfort zone. You need to pray the Blood of Christ over yourself, as your intercessors need to as well. The Blood was poured out to cleanse our flesh, and you need to get some. And them some more.
And Demi is right in something else... all hell will break loose on you. Go into this half heartedly and they will eat you alive (you think it's bad now).
Prayer, fasting, and finding those who aren't afraid of those things to pray over you... then confession and rebuking the powers and principalities... discipline in the flesh... all of that renewing your mind and refreshing your spirit. And all of it, every single ounce of it to the glory of God. Demons HATE that glory to God stuff. Stick it in their faces. And go big or stay home.
1 Corinthians 12:
3Therefore I want you to know that no one who is speaking by the Spirit of God says, “Jesus be cursed,” and no one can say, “Jesus is Lord,” except by the Holy Spirit. When these things try to invade your mind, just start repeating that. Jesus is Lord. Jesus is Lord. Jesus is Lord. Speak it, there is power in the spoken word whether it's in a whisper to yourself or a shout to the heavens. Since you must have the Holy Spirit to do so, it will affirm the Holy Spirit's presence in and around you. Make place for Jesus in your heart and mind and lips and dwelling and there will be no place for them.
God bless you my friend. You picked a deep pit to have to rescue yourself from. God can do it, but you're going to have to do your part to receive it. No more ms shy girl, this is a fight for your life. Jesus died just so you can win this fight. let that be motivation to persevere - knowing that in the end, it's not you who wins it's Him.
