I pray. Long ago I realized that there are very few things that have the right to claim my sanity! And even then, I'm not going down with out a fight or a passenger (because it would be someone incredibly close to me) who was determined to send me over the deep end.
I've found that my worrying wont fix a problem. I have to be proactive. Learning to know who I am and accepting myself I refuse to let someone else's bad day or drama filled life determine who I am or how my day will be.
For the most part I've set myself a few rules. If I'm the cause of my problem, I acknowledge it, full responsibility. If I am on the receiving end of someone elses' crap, I shake it off and if needed I inform the offender depending on the severity. Most times they don't know that I'm pissed. I work proactively to change my situation and I look at the worst possible thing that can happen and realize that in the big scheme of life, it aint that big a deal.
I'm speaking from the I've been there perspective. When I say some really bad things have happened in my life I can say from experience that had I not had my faith (Christianity) I would have lost my mind. It truly brings me peace. Thats not to say that I don't have bad days or that things don't get to me or that I'm not anxious because I am. I'm human. What I am saying is that my faith carries me through and gives me strength. Lifes blows, when they come, don't leave me floored.
