I've heard it said that what it takes us to survive is far different from what it takes to live a healthy and happy life.
Mind you, survival is not to be taken lightly. It's a huge accomplishment. Life can contain so many hurtful and life-altering circumstances. It can take everything we have to survive some of them. But once we have survived the difficult or painful thing, we need to refocus our life to see what's needed to live in a truly life-giving and healthy way.
Do you see a difference? For example, if you've faced cancer and had to endure surgeries, radiation and/or chemotherapy, you've no doubt had to pull away from all your commitments and perhaps even some of your friendships in order to conserve your energy. You're pouring all your energy into healing.
Once you have healed and come out on the other side, you may be more selective about those activities and friendships you re-engage; but you will definitely not want to isolate. You will need the support and love of friendship groups. You needed them during your survival time, but I'm guessing you didn't have as much energy to give to them then. Now you can refocus and re-engage in a new way. The choices are yours.
