depressive things in life that affect us

It would appear to me after many years of experience in this life that we are thesum total of not only what we experience but even more so the experiences of those around us. Primarily relatives that are close to us, but also friends and acquaintances. I say relatives because they are deeper into our feelings. Their closeness makes us vulnerable to their reaction to their experiences and it becomes a part of our own in a less intensive way. Would you agree. I have found it is impossible for me to delete the affect others have on me. I'm like a computor, delete will not take it off the harddrive of my mind. Wouldn't it be wonderful to just absorb the good feelings and not the bad. I try to concentrate on things that are on the upswing and depress other disturbing things I cannot control to the storage part of my mind. Your comments and suggestions are welcome.
