Many therapists are doing a certain amount of pro bono help now due to the pandemic. Search around and maybe you will find one. You also can do tele-mental health online appointments from your own home.
Joining a church of some kind does seem to be the community feeling you are looking for. Maybe try a few different churches and see how you like them. At least in these churches you will have freedom of thought. Most churches have many social things as well, yes, even during covid though on a more limited basis. They also have ministries that help people with daily needs, sickness, loneliness, food, etc.... Volunteering would be a great way to make new friends!
I wish you well and hope you do not feel that the jw's are the only way. There are many options out there.
