Like Sarah says, learn to love yourself first. As individuals we know what makes us tick and so ask yourself what makes me tick as opposed to what do other people do to make me tick.
Also if you are constantly putting yourself in the realm of need and want, that is the message that you are sending out to the universe and nothing will change. Think of what you have already in positive terms, of how you are blessed. Be comfortable with you.
I wonder if you have ever tried any form of meditation or used positive verbal reinforcement or affirmations. I know that on this site there are links to sites that can help you with this. One of my favourite books is Symbol Therapy by Ulli Springett.
Look at how you can spend those hours you are overspending at work to do something creative - find another aspect of yourself in this. You will have so much fun doing it. Have you heard of The Artist's Way? Look into it....
I wish you all things good.
Love light and peace
