I second the search past threads suggestions...it's tedious, but after being a member of the Forum for many years...almost everything has been discussed ad nauseum.
I'll also add that volunteering in community service may be any volunteer position that puts you in circumstances that allow you to empathize with others in distress - this is a highly useful skill to have BEFORE you begin graduate school for clinical psychology. Look into schools (although - they may be filled by those interested in teaching or school psych), hospitals, suicide hotlines, domestic violence programs (like shelters or advocacy programs). When I trained at an outpatient hospital facility, there were volunteers who would play with the children in the waiting room as they waited for their therapy or medical appointments. There are many volunteer positions out there...find one best for you (it doesn't have to be in mental health, but best if it is) and tweak the experience so it matches your growing interest in the field; for example, say you hone in on an interest in psychotic disorders (stemming from your abovementioned interest in "abnormal disorders"), and you find a volunteer position in pediatrician's office...you can begin to see how parents relate to their kids (or not) and how it plays out in their behavior...then, think about how those kids will grow up and how those parent-child interactions may influence a hypothetical diagnosis of schizoaffective disorder. There's a lot of supposition in my example, but make your experiences work for you. And all of it will help guide your general interests to be more specific.
Most volunteer programs require you to be 18 years or older, and it is important to be mature and professional when volunteering. I screen volunteers for a domestic violence advocacy program where I am a volunteer, and maturity & reliability are both very important in the initial screening process because without it, you are turned away to be a volunteer. These experience are all great prior to application time, especially coming straight from undergrad.
To the OP: without the intention to debate PsyD vs. PhD (search past thread on that topic - for sure, and
I will discourage you from starting another debate on your thread), there seems to be a great misunderstanding in that PsyDs are more clinical than PhDs in clinical psych. When a PsyD exits most programs, he/she is deeply aware of the scholarly effort that goes into any degree in clinical psychology - whether they conduct independent research or not (as most PhDs are required to conduct their own individual research, i.e., at the very least, the dissertation). I'm suggesting to look into both PsyD and PhD programs in your ultimate search. There will be good and bad programs for both degree types.
Good luck!
*Edit: And if others seem to be discouraging you, it is because you really need to have a scholarly interest to carry you through the training (whether it be PhD or PsyD in clinical psych)...or get masters level-therapist training or a social work degree...although those PhDs in Social Work usual rock out with their research.*
