Thank you Aura and Cameron

I'm not a native speaker, but I’ve been studying Japanese for a long time. I don't think it's typical to say いい気、I've never heard anyone say that before. I have friends who usually say something like 電話をもらってよかったです！ or　電話をもらって嬉しいです！If you use 気持ち for receiving a phone call, it sounds strange to me... Words like 気持ち I've heard used when someone goes into the 温泉 and they say わー気持ちいいですね！(Oh it feels good, doesn't it!) 気 really seems to be like something related to the atmosphere, a force, a feeling, a mood. 勇気、電気、天気、気温、陽気、気分・・ Many words exist using 気。

For your example sentence, I think using 気持ちでした or maybe 気持ちになりました is fine. Because 気 by itself seems to have a more spiritual meaning, I often see it used in martial arts etc. Not really used for feeling good. That is just my take on it anyway.
