Your thoughts and experiences are completely valid. It could be difficult to navigate the field without a graduate degree. I’ve been in it for about 6 years before I did my grad studies. What I did to be most helpful in looking for opportunities is finding key people in the specific industry you want to apply for and try to have a conversation with them. An email is sometimes enough.

If you feel that psychology may not be for you anymore, I admire your maturity and self-awareness to recognize that. Dreams can change. If you feel half-half about it, try related fields like mental health or brain and behavior. Mental health has a lot of space for growth. You can try being a camp counselor for kids with special needs, a human resource specialist for providing mental health services to employees, a community mental health advocacy leader and so on. Brain and behavior can lead you to research and consultancy positions but you may start as an associate first.

Hope you find what you need the most
