@sharlynn62 - That sounds like an excellent plan. I hope that you have a huge success with it. What has helped me is my blog and writing on here. I can blow off a lot of steam from my triggers just by writing. My twin, who died several years ago, was a borderline personality and drug addict.. She was some tough character. My blood would boil every time she called because it meant that she wanted something. I wont bore you with all the details but I also feel guilty that I wasn't more understanding. I think that she just wore me out. I've almost come to terms with it. But if I hear a person with her tone of voice I cringe and get angry.

Here are several tips on dealing with triggers.
