I understand being scared, we all are the first time asking for help, but you just did the hardest thing and asked. I managed to quit for 5 years before a year ago with only myself and a few close friends support. it didnt work so i came here for support for the moments i feel weak. As for tools you will find many opinions here. My advice is to look at them all honestly and see which one matches with you the best.
So glad you are here,
