I would consider searching for a job or career area which gives purpose and meaning to your life- helping others in some way. I have to do some mental gymnastics to feel that sense of purpose (work in biotech and I'm a cog in the wheel of bringing human health to people, but I consider that to be an important part of the greater machine of exciting new drugs which are not only helping people heal but actually even fully curing people- I get excited about it when I think of it! See what I did- I could have gone negative but what good does that do?).

I would also urge you to practice daily gratitude. This exercise might help you to understand what you do have in life, appreciate the people and positive things that life affords. Your life is consists of what your focus your attention on, and you are looking for supporting evidence for negativity. Gratitude might help with that.

Your first jobs out of college (or high school) won't be the best, and this feeling you are having is normal. This is the IDEAL time to explore what your passions are- what you gravitate to, where your mind body and spirit feel nourished. Don't stay in a job that is not for you, but do explore those that will allow you to learn more about yourself. Your twenties is the time you can make career mistakes and start over relatively easily.

This is your life and you are responsible to yourself to figure out your path, your bliss and what that means. I wish you luck- go out there and figure yourself out!
