An adjective in a poem (Eng)

Dear linguaphiles,

In Russian there is an adjective - "грубый" - which, in a poem, collocates with both "[love] confession" and "life/destiny". Its lexical definitions are: coarse (fabric), rough (fabric, skin), crude (workmanship), common, vulgar, unsophisticated, too straightforward, tough, rude, hard, hardened (hands) etc.

I need to find a similar one in English. If there are any. So, could you help me to find an adjective which would collocate with the both words in brackets and mean the following:

1) simple, too straitforward, a little bit vulgar, common, unsophisticated, too frank --- (confession/speech)
AND
2) tough, difficult, full of misfortunes and painful emotional experience --- (life/destiny).

Thanks a lot for any ideas.
