After losing everything, my cat got sick. How do I deal with this?

Please refer to my last question about how am I to deal with my life partner leaving me, after my family said things about her they cannot take back and now I have written them off because all they do is attack me and want me to take pills for my emotions. My cat had to go to the Vet ER last night, he has crystals blocking his bladder. Crap, I am going to Netcare. I can’t deal with any of this anymore. Not going to hurt myself, but would still like to hear from whoever is out there that can offer any hope, care or anything good because I need something good and I need it asap.
