I remember when I got hired to work on old code for an autoshop program. I actually loved it... great job though it could be tedious, but the worst thing was the boss constantly micromanaging me. I couldn't stand it. We'd have meetings about fixing things and new code to be implemented, than he would have me email him [an outline of] everything said in our meeting.
Then he would critique it to exactly what he wanted me to know about what I should have gotten out of the meeting. I'd say I spent about 3 or 4 hours a day coding and the other 4 was pretty much dedicated to putting up with his antics. Every time he would come bother me, I'd lose my focus and spend 10 or 20 minutes just trying to get into that mindset again.

Long story short: I ended up applying to other jobs because with $40k of student loan debt and being paid $12/hr, I just wasn't ever going to move out of my mom's house. When I told him I was going to be getting another job, he offered me double my salary to stay. I thought about it and knew that he was going to hold it against me for everything.
Towards the end of my time working there, he did give me a raise for what would last a week and allowed me to work nights, so I could work in silence, as a way to try and lure me to stay and give me the "experience" of making $24/hr. Unfortunately, he also installed spy software on my computer, and questioned me about why I was on YouTube all night (I had a playlist in the background) instead of doing my job. After that, I pretty much told him it wasn't going to work out because of his mistrust of me, and I cut my final 2 weeks short.
Anyways, I ended up getting another job and this one too -- I worked on a "cold client base" that was at least 2 years old -- basically, the company sold contracts in advance and never delivered, so I was hired to help them catch up. Managed to take their "cold client base" from about 140 accounts all the way down to about 32 accounts remaining. It involved some software and collecting data. We worked in Flash. Other companies were working in HTML5.
We had an in-house programmer working on an HTML5-based platform and it was amazing. Unfortunately, I got laid off before I got to learn the new program, but apparently, after 6 months, so did everyone else and the company went out of business. Had they just released that program and pushed it, I'm pretty sure they would have been able to stay in business, but such is life.
I currently work as a web developer for a large media corporation. No regrets and I've definitely earned my salary and raises over the years. If you aren't feeling it anymore, than start looking for a new job and go for it. You have programming knowledge so it is likely you can get a job in many different places. When you go, they'll probably find someone else. We're all replaceable, for the most part.
Go do something you enjoy and get paid to do it. No sense in wasting your life away not doing something you don't really enjoy.
