I think there's a part of all of us that always feels that way. Sometimes, it rests quieter than at other times.
Are you new to where you live? Do you have access to a therapist?
I hope no one here ever thinks of making fun of you. Those feelings are legitimate. If anyone does, report them to a moderator ASAP, and block that member (place them on your Ignore list).
I know I have felt that way when my anxiety got very bad, a few years back.
Please let us know if there's more we can do for you.
