I wish you the best of luck .. I so understand the difficulty to find " good things to talk about " its exhausting and honestly a pain in the *****... I most bipolar people deal with this problem ,, I know i certainly do ...

Try and have a good time and hopefully your boyfriend can keep the conversation going and you can just kinda chime in occassionally and just maybe look forward to eating food you didnt have to cook or clean up the mess hahaha ,,( ive done that before and its gotten me thru )

Good luck and wishing you peace , love and the strenght to get thru this outing <3
