should I just pack it in???

[Snappy]

From a distance I think my tank looks not too bad, if I do say so myself, however up close and personal you can see several acro's are sick and are ready to die a slow RTN death. In the past 6 weeks or so I have lost about 7 colonies and several others are browning out on me. Due to my new job as of last fall I can't seem to keep up with the maintanence anymore and feel like I am fighting a loosing battle. I was going to build a bigger tank; fully automated, complete with a fish room, but don't know when I can get to that size of undertaking and then to move everything into the new tank will take weeks. I love the hobby but I am ready to give up. If I didn't have about $12K invested in the last 20 months it would be a no brainer. What should I do? Should I admit defeat? I need some advise or perhaps even a pep talk. I just know neither the tank or I are happy right now.
