Am I? Or am I so sane that u just blew your mind?

Junkwar, You are only partially correct. You do need to let the PSS analysis know that the circuit is autonomous (an oscillator) by specifying a pair of node to the PSS analysis. The voltage difference on the nodes should have a significant component at the fundamental frequency, so they could be connected to the output or perhaps to the resonator (the nodes do not load the circuit in anyway).
The warning about the period being too small is an indication that the voltage difference on the nodes is constant valued. This could be because you connected the PSS analysis to the wrong nodes, but more often it is because the oscillator is not oscillating.
In an autonomous analysis, there should be no sources that produce a time-varying steady state signal. So you should get rid or the psin source. If the oscillator really does start, the simulator will not converge because there will be two different periods present.
