Agree! To add to the discussion, I believe that having a solid theoretical orientation to work from is important, so that rather than feeling like you address wide-ranging concerns in a piecemeal/haphazard way, you have solid grounding regardless of the presentation. Depending on your orientation, you might view issues as attachment-based/ego-based, or thought distortions, culturally-influenced, existential/spiritual crises, emotional avoidance, issues needing reinforcement or extinction, interpersonally-based, or a combination, etc. Once you feel solid in your theory (theories?), you work from your orientation and (appropriately) incorporate other interventions that are helpful, and seek additional training in areas that you’re less familiar with.
The nice thing about working in group settings is the wealth of knowledge/experience shared, so I would strongly suggest consulting as needed and making good use of the expertise of the seasoned clinicians around you.
