I don't think age has much to do with having less buffer. Perhaps you've been stressed out for so long that it's harder to cope. That's what happened to me. I used to be able to handle stress well, but after a few years of extremely stressful incidents, I broke down. Now, I can't take stress as well as before.

One of the things I understand now is realizing when I need help, and ask for it. The longer I put it off, the worse it gets.

There's a lot of healing to be done, and seeing a therapist and/or going on medication will help.

Keep posting here, we're a bunch of good listener, and we care.

Take care (((((((((((((kv))))))))))))))))
