I appreciate your understanding as we try to ensure the agencies have the volunteers needed to provide the essential services they provide to the vulnerable population they serve. THANK YOU: This CMG Gives Back event provides an opportunity for YOU to get involved in helping others! Benefits go well beyond the help we give to others. Volunteering provides a wide range of personal benefits, including positive effects on mental and physical health, reduced stress/depression/anxiety, increased happiness and improved purpose, life-satisfaction and personal well-being! Plus, the opportunity to get involved, connect with others and help those in need. PARTNER AGENCY: This event is hosted by Lutheran Social Services (LSS), which serves thousands of people in need each day in 27 Ohio counties by addressing the four core societal issues of food, shelter, safety and healing. LSS offers food through the LSS Food Pantries, housing and supportive services through LSS Faith Mission and LSS Faith Mission of Fairfield County homeless shelters, domestic violence services through LSS CHOICES for Victims of Domestic Violence, senior living and health care, affordable housing communities, and other services that uplift families and strengthen communities.

Wouldn’t it be nice to find a way to overcome your feelings of anger so that you not only control them, but you no longer have the urge to lose your temper in the first place? And how about being able to shake off resentments, persistent annoyance, or even feelings of vengeance? We’d like to invite you to an event on how to overcome anger and resentment. We will show you why people have trouble controlling their temper and where resentment comes from. Flaring anger can ruin a meeting, a relationship, an opportunity, or just about any aspect of life. Worst of all, outbursts towards our family can create hurt that lingers throughout a lifetime. You want to have a civil conversation, and you’ve vowed that you wouldn’t lose your temper, but a few minutes later, the anger flares up. Maybe you’ve realized that being angry doesn’t get you what you want so you internalize it. Or maybe you avoid the knockdown, drag-out fights, but stewing in resentment is exhausting and takes an emotional toll. In this event we show you how to get to the root of your anger so that it stops being an issue to you. You’ll also learn why people harbor resentments and how to move on. Don't continue to struggle, make a difference in your life, and join us for this local event. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This Meetup is sponsored by your local Dianetics and Scientology Life Improvement Center.
