The emotions in the subjunctive.
Hola a todos 
Lately l've been studying the subjunctive and l'm having a trouble understanding the letter E (emotion) in the W.E.I.R.D.O verbs!
l'm not sure about the explanation, why do you use the Subjunctive with the emotions? and when to do that?
l know there have been thousands of threads opened about the subjunctive before, but l can't seem to find an answer to my question.
Any examples are very appreciated!
Thank you so much ^_^

I don't! Look:
¡Es una tragedia!
¡Qué contento estoy!
Subjunctive is used in subordinate clauses, when the verb in this clause is not being used for the sole reason of communicating what you think it is right (or might be right) about the world. I guess what that weird W E I R D O means is that in sentences like this:
Me alegra que hayas venido.
you are not saying "you've come" (hayas venido) to inform the other person that you know or believe that he has arrived, so subjunctive makes no sense. However, notice that in
Estoy feliz porque has venido
you are clearly saying "(because) you've come" to highlight the fact on its own, regardless of how you feel about it.
Sigh! Why does he always give a better answer right before I post mine!
The subjunctive is a verb mood, not a tense. Mood refers to the attitude of the speaker toward the action/condition of the verb - how likely/factual the statement is. The subjunctive mood is subjective; it expresses emotional, potential, and hypothetical attitudes about what is being expressed - things like will/wanting, emotion, doubt, possibility, necessity, judgment. The "normal" verb mood is called the indicative and is used for factual or definite statements about reality.
Yo temo que... The subjunctive can be used if you wish to express your subjective reaction towards the action in the subordinate clause, not declaring or informing of the verbs action.
Estoy sorprendido de que...
Me siento que...
Me alegro que....
Es lástima que...
Es triste que...
All of these main clauses can be used to expressing your subjective opinion or emotional response to the subordinate clause action rather the declaring/informing that verb's action.
However, if you wish to inform the person of the action in the subordinate clause then use the indicative.
It is sad that he will announce his resignation tomorrow.
If you wish to empahisize your feelings use the subjunctive. If you wish to inform that the resignation will take place tomorrow use the indicative mood.
Remember that the mood expresses how the speakers sees the verbs action (as subjunctive or indicative); and his verb mood choice helps share that viewpoint with his audience.
