A challenge you might get on board for is to find the kind of mental & emotional conditioning found OUTSIDE of religious perspective. That way, less cognitive dissonance. Ditto, whilst early childhood education, kids sports, etc. are rife with laying the foundations for strength, confidence, morality, etc.? Might hit a little close to home coming from childhood trauma. But those are really only 3 areas where people intentionally shape their minds and hearts.
Therapy, is very clearly one of those places. You're already doing that.
Team & individual sports.
Collaborative arts.
Volunteer Groups
Etc. (Aka it's more fun to discover them on your own than be told ;) But a scrap of a treasure map is always useful, neh?)
Pretty much anywhere you find a group of people working together towards a common goal? (that isn't money / aka jobs, although some jobs are extremely motivational & self building; for example military, police, fire / most jobs aren't) You will find methods & practices that are designed to instruct & shape the hearts and minds of the practitioners. Whether it's habitat for humanity, or YMCA, or a dance group, or martial art. Some groups are far more open/direct about intentionally shaping their members. Others it's just something of a byproduct. Each program will have different messages they teach people to believe about themselves and about others.
HINT : Look for teenagers. "Normal" human development* teens are only just deciding who they are & want to be & naturally gravitate towards areas that shape them into the people they want to be. Which means that savvy adults? Market themselves towards teens. Whether it's at risk youth or the most exclusive "enrichment" & "well-rounded" activities to pad college applications. There are always always always adult beginner programs where there are teen programs. Adults simply have less time, in most cases, to devote... And the urge to define and create ones self usually wanes the more people do define themselves and come to am equilibrium in thought & practice.
* Human development is incredibly fluid. What's normal for teens in the west isn't what's normal for all teens everywhere in the world. And sooooo many things table that process -like trauma- for many people. But since you live here in the states? Look for programs geared towards attracting teenagers, then look into their adult programs. Whether it's sports, arts, sciences, maths, engineering, activism, volunteer, etc. Choosing your own messages? Not just accepting what other people tell you about yourself? Is the hallmark of growing up :) Most people start that process as teenagers. Some of us don't start until later.

Upside to finding groups whose messages you wish to incorporate into the way you think/feel/act? It dovetails quite neatly into wishing to start making friends and being more social. It's rarely an instant thing, but shared experience & perspective is usually what brings people together. So you go for yourself, and in the process? Often find other people.
