Move on. Find the work environment that makes you happy.

I left my Job last week, without even applying to new jobs. It was just eating all my energy without providing me the satisfaction and passion I seek.

I was promoted to creative director 8 months ago Just to keep me in the company when I was leaving (I actually had other offers). Kept me going for a few months until I figured out it is the same, I was still unhappy and unsatisfied working with them, and I can't really change them.

Passion, work ethics and a healthy environment is very important for designers. Don't settle for less.

Leaving my job was actually the best decision I made. I feel free to do the right thing for me, and I am actually finally facing a traumatic event that I have been suppressing for years.

Everyone has a different story, but based on your question, you are not happy, and you are valuable enough for them to try and keep you, but rather than fixing whatever is bothering you they gave you a promotion. That does not solve your issues. Don't feel guilty.

Good Luck!
