Sounds like you're burned out, my friend. There's nothing wrong with you. You're not broken. You've just had too much on your plate and you need time to rest, heal, and take very good care of yourself at this time and be gentle with yourself. There's nothing wrong with taking a break when you need it. Don't feel guilty about that. It's obvious you need a time of refreshing and rest. Never feel guilty about that. We're not called to give of ourselves until we're exhausted or it's beginning to affect our health. Friends will understand. If they don't, and by the way you don't owe anyone an explanation to take time off and you don't have to explain yourself... But a friend will understand and if they don't, that's not your problem, that's theirs. You have overextended yourself and now you're suffering for it. It's time to be gentle when yourself and take much needed time for yourself so you can begin to heal. We don't have to keep performing or pleasing to keep friends. That's not what we're called to do. It's freeing to let things go if you need to, and even people if they are toxic to you and causing you stress or anxiety. Love yourself enough to do what you have to do. If yourself permission to live life on your terms, not other's.
