Karma? I need a chance.

Dad landed in hospital today. I feel so useless. I can't support anything. I'm jobless. I'm stupid. Getting result soon. Dunno if i had done too badly or what. I'm not contributing to anything. Is it karma cause my mouth always say things that sound very ugly and hurtful to ppl? Or what? I hope my life change soon. Please give me a chance to change my situation now.
