解說
Used to say that something caused a bad result. It puts the responsibility on that cause and can sound like a complaint or blame. At the end of a sentence it becomes 〜のせいだ. 〜せいか means "perhaps because of ~" when you are not sure of the cause.

注意
Use おかげで for good results. 私のせいです is used to admit your own fault. To state a cause neutrally, ために or ので fits better.
