Step back! You have great skill sets.

But you should not work as a slave and doing jobs which needs a whole team. You need to:

1. Start looking for a new job, with much better support;

2. Can you handle a team of DBAs and IT guys, e.g. enjoying being a manager? Move up!

3. Job and money is not every thing. Do you have family? Kids? or you are too young for that? Try enjoy life.

I hate to be managed by idots, who reboots application server without approval and during peak hours.
