Father Yahweh, please hear the heart of this dear soul. Allow Your Holy Spirit to let this dear soul know that he/she is never alone. You sent Your son into this world that we may have life MORE abundantly.
Send the gift of praise into the heart, soul and mind of this dear soul.
My dear brother/sister (sorry but don't know your gender), there is nothing wrong with being alone with God. Sometimes, there are days that I wish to have some alone time with my Father. My days get so full sometimes that I just want to scream.
About having family members that are not living Godly lives, oh yes, I truly understand. We are in this world, but we are not of this world, according to our Father's word.
But, don't fret because of evil doers. You are right to separate yourself from among them. That is a very strong temptation that you surely don't need.
But, don't feel like the lone stranger. God know exactly what He is doing in your life. Just listen to His still small voice as you fellowship alone with Him. He will speak to your heart and cause you to praise like never before.
I think back when my days were more peaceable. I would have a shouting good time, just me and the Holy Spirit. I would put on some good gospel music and just shout and cry. I would praise God so long, all I could do was go to sleep when I got done
Now, I have a five year old asking me a ton of questions, and a husband that is more a baby than the five year old
So, just know that God will do just what He said He will. He will pour out His spirit on all flesh. So, allow His Spirit to comfort you and lead you each day on walking in His righteousness. Whether you are in a crowd or alone at home, praise him any how

He will tell you where to go. He will meet all of your needs and He will never leave you nor forsake you. Amen!
Father, please be with this dear soul. Touch the heart, mind and body with Your wonderful spirit. Put praise deep down in his/her soul. Let him/her rejoice no matter who is in the presence. Meet every need for this dear one. I ask this in Jesus name. Amen!
It won't be long now dear one. We will be awaiting the praise report. Hallelujah! Hallelujah!
