Need suggestions

I am currently not the liking the work in my team. Everyone is overworked because of which they are not able to provide proper training for months now and somehow expects me to gain all the knowledge by myself and be fast and always available. They also expect me to take sole ownership of the work without support soon, probably by the end of this month. i joined this team 2 months back. I am really anxious all the time and want to quit. I am not happy with the tech part of the work. It's too much tech which is honestly not my background. I want to switch to a non-tech product based company. Any advice or suggestion are welcome.
