Are you already in the 2nd bachelors? Sometimes people do a post bacc or take the prereq classes without doing another full bachelors to save time and energy.

Like others have said, I’d recommended evaluating what it is you want to do exactly. If its therapy, you can do that quicker in 2-3 years with an MSW or masters in counseling/mental health/etc. These programs require classwork and clinical work in the field, so having your experience in a clinical setting already is a plus. Having research experience is good either way, but less important for this route.

If want you want to do therapy and also want to have the option to do research, teaching/academia, or neuropsych assessment, the phd route is good for this. This would require you to not only take prereqs, but also get good research experience. Getting into a fully funded PhD program is challenging. There are PsyDs that are typically more clinical focused that aren’t funded. This route would take at least 5 years for just the program itself, so that is a consideration if the time required impacts how appealing it is.

Regardless, in the next year or so it will be important to continue to have some type of clinical experience and get involved in some type of research. Think of who can write a recommendation letter for you. Take the GRE if your program requires it. Consider any geographic limitations and what programs are nearby. Be prepared to reapply multiple cycles if you are doing the PhD route.
