Fair Sarah, I am sorry you are hurting. When things start to spin sometimes it feels like a tornado, and you can't get out.
May I suggest that you see your doctor. I have a feeling that you are suffering from true depression. Medicine can help.
I know that is not the "fix" for everyone and perhaps not for you either, but the way you are feeling is not healthy for you or those around you.
Medicine is there to help if it can. If not, then maybe your doctor can help you pinpoint the problem.
Not all medicine is permanent either. Sometimes just a helping hand until you can get your feet back under you.
You are only 21 and you have children. Ah it is not easy being a young mother. You are still needing to have fun yourself.
Being the mother of five and knowing how little appreciation we receive at times it is really very normal to be frustrated and unhappy. Sometimes.
You most likely hear "mommy I want" mommy I need" "no!"
Very rarely do you hear "thank you Mommy" or even "I love you Mommy" not in those early years.
Being a parent teaches us true service to others.
I remember when my daughter looked at me and said "all you do is yell" I wanted to yell again and say No I don't! But guess what? She was right. And she was all of about 10. After that, I made a choice to not yell anymore. It wasn't easy and I wasn't always perfect but it was a huge improvement.
I learned to talk to them and explain why I felt the need to yell. Because no one listened to me when I asked nicely! They would only respond when Mom got mad.
You said you rarely take time to exercise. I would stress how important exercise is. The natural endorphins that we get when we exercise is right up there with Prozac. Really! That's why they call it "runners high"
Find someway or someone who can give you a break for an hour and go workout. Get away. Swap kids with someone so they can too.
But please seek help other than just on this forum. We care, but I think you need a little more support than even we can give.
If you would like to pm me please feel free. I will get back with you as soon as I am able.
PS I worked out today too! Ah feels good! But I enjoy lifting weights. My joints and muscles both hate me and love me. LOL
Thinking of you Sarahfair
