Read as much as you can from various authors to strip your mind of JW teachings, I'm sure everyone here can recommend a book that helped them. It will help you to make new friends and connections once you no longer see yourself as different, you're not different, the JWs made you think that, what we all carried with us to some extent is trauma. But many people carry trauma, from abusive relationships, bullying at school and work, and so on. Meaning that you will find people in the 'world' with experiences similar to yours, and feelings like yours.
Joining local classes, art/dance/exercise/gardening, a gym, community clean ups (like town/beach etc), a local school for adults/college evening classes and courses are all ways to meet new people who have at least that interest in common with you.
You can still pray, you may choose to drop the name Jehovah because of the religious associations, and just use Father, Heavenly Father, Abba etc. Whatever feels right to you.
I personally found Eric Wilson's book very eye opening, How They Shut The Door to the Kingdom of God. Others will recommend Franz's book, I can't remember the title, I didn't read it yet but it's on my list!
This forum is great for at least virtually meeting others who have lived your experiences and they will understand you.
May you find true community, and joy, and meaning. Much love x
