Well, you know, some of that may not be emotional, it may be medical. So, you might want to go over that with your regular doctor.
Go over blood sugar issues, various things.
Here's one motivation trick. Athletes use it a lot. Say that you have a routine of jogging 5 miles every morning. And many mornings you wake up and think..."Oh, there is no way that I am going to jog 5 miles."
So, the trick is that you say to yourself, "Ok, today, I am not going to jog 5 miles, I am only going to jog 1/2 mile." So, when you do that, your mind relaxes. And then when you start to jog, your adrenaline starts to kick in...and by the time you hit 1/2 mile, you rarely want to quit.
And you can do the same thing with any task. Say the basement needs an hour of cleaning. Just say to yourself, "ok, I am only going to clean for 10 minutes." Then, when the 10 minutes is up, your momentum is engaged, and it is easier not to quit.
take care.
