I am sorry
I hope you will find the motivation to start an excercise today. I know that feeling of not wanting to move, not seeing the good it will do.
I am finding that being outdoors helps me a lot. I love to hang out clothes but when I am in the house it doesn't seem like a fun thing to do. Then once I go outside, I am so glad I did.
If it is a nice day where you are at, try going for a short walk.
For years and years, I used to force myself to get out of bed and out of the house. So strange, I KNEW that once I got going I would be just fine but that knowledge had to be pulled out of myself every morning. It had to convince me every single day. I loved school and my jobs but I still could not get going in the morning. I would wonder if I should just drop out of school or quit my job because I was too depressed to deal with moving in the mornings.
I would tell myself that if I got to school or work and still did not feel I could go further, then I would go home. I never made that return trip home. But even so, it was still a daily battle to get going, to find a motiviation to move.
I hope will feel better this afternoon and evening.
