Unless you love your job,could be time to have a Big Think.
I understand not everyone can leave their job, but if yours is causing you a dread, then you should seek to change it. Really.
It is your right, to do that so when you do wake up....those feelings are not there.
Write down on paper, what you feel would not make you unhappy to do all day,(as in the way of a job).
Think, is there a course you can do later, that would allow for you to work partly from home? write down every thing you can think of.
Tell yourself, you have to make the change, and it will come about.
I have had in my 40 years of working life(nearly 60 now) only 2 jobs!!
That I LOVED, like I got up and couldn't wait to get to work.Both where I knew I was not only 'needed' but I was making a huge difference.
Without my skill and desire to make a difference, I could not do that job.
Look at what you desire to do, to help this world...and feel good, and Enjoy,
doing it.
It could be something like looking after children in a day care centre, or if you like cooking working in a kitchen.If you like people, work in retail.
But.....whatever you feel is your 'like' write it down...go from there.You will be quite surprised how it can become a love.Also don't forget to write down a passion you have, see how you can tie that in.This is your life, and you deserve to be happy in a job.
We need more people, who love their jobs, because they will make the world a nicer place too. :)
