à cause du fait que je sois coincé

Hi Gabrielle,

Haven't read the text but suggest may be that one is expressing some frustration / emotion therefore the subjunctive which would highlight the emotion aspect?

Hope this may help.  Alan (Jim) 

I thought this was a very good article on why 'le fait que' sometimes requires the subjunctive:
