Searching for Calmness

Like I said previously, I have had some days off this week,,,,,,and it has been really nice. I have worked hard around here,,,,cleaning and organizing,,,,,,but I have had time to enjoy too!
In the last few years, I dont know what has happened to me,,,,,I guess I'd say this has happened to me since I had my daughter and she is 7 years old now,,,,
I used to be this mellow, calm, laid back person.
Not any more!
I used to have hobbies that I LOVED! Cross-stitching, Painting, Bird watching,,,,,,
Not any more!
Now, If I sit down and do something that "I" enjoy, I feel guilty the whole time,,,,because there are so many other things that NEED to be done,,,,,How can I just sit there and do something for FUN???
Now, I am almost ALWAYS a bundle of nerves! When I am awake, I cant rest,,,my mind is never at rest! I always have a MILLION things on my mind!! ALWAYS!
I have to say, I am thankful,,,,,when I lay down at night, I am out like a light! and I sleep like a LOG all night! Sleeping has never been a problem for me!
But when I am awake, I am a nervous wreck! I just feel like there is NEVER enough TIME! Guess I obviously dont manage my time very well!
My best friend, Robbin, who is 10 yrs older than me,,,,,she says this PHASE of my life will pass,,,,Right now I have a full time job, I have a husband and a 7 yr. old daughter who "NEED" me!!!
In my heart, I KNOW there are people out there who are so much BUSIER than I am!!! But maybe I just cant handle all this "busy-ness" like others can!
and then I look back on other phases of my life when I wasnt very "busy" at all and I longed to have more,,,,,,,,more to keep me BUSY!
I guess it is just the fact that I am human,,,,,,I struggle to find "contentment."
That sounds AWFUL! That sounds like I am just this miserable, unhappy person,,,,,,and I'm NOT! I just want/need some "calmness."
I feel guilty even saying all this!! I keep thinking of the verses in the BIBLE where Paul said "Rejoice in the Lord always,,," and "I am not saying this because I am in need, for I have learned to be content whatever the circumstances. I know what it is to be in need, and I know what it is to have plenty. I have learned the secret of being content in any and every situation, whether well fed or hungry, whether living in plenty or in want. I can do everything through HIM who gives me strength." Phil 4:4 and 11-13
It is just a weakness in ME,,,,It is a "chink" in my armor,,,,,and something for me to pray about,,,,and something for me to work on in my daily life!
