I want this year to be OVER.

I honestly don't know how much more I can take. Anyone who knows me, knows the crap I have been put through in the past year/ year and a half. I know everyone has bad times, of course. I just feel like this has been the absolute worst year for me. There have been so many changes, obstacles, tests of the human spirit....I didn't realize a person would be thrown so much in such a short time. Another one of our cats ran away sometime on Monday. We realized he was gone last night. He hides a lot, so it wasn't all that strange we hadn't seen him in awhile. He was my Sir Fatticus, real name Nathan. I feel awful because when I last saw him Monday afternoon, he was on my bed, rubbing on me as I grabbed my purse , and I shooed him away because I was in a hurry. Now I feel like absolute crap. Addy ran away when I was in Ohio last month, and now Nathan. I am so sick of everything. I feel like an utter failure sometimes. A COMPLETELY MISERABLE FAILURE OF A PERSON. I am 25 years old, I have nothing to show for my life, no job, no house, no real possessions (things worth something significant), no significant other, no headway towards my dream, no leads. I could go on and ON. I am NOT at ALL superficial, I just mean, things that appreciate in value, or look good on a credit report. I feel as if I ruin everything, or make things worse. I constantly make mistakes. I know it's silly because no one is perfect, but it just seems like I can't get anything right. I am wrong about everything. I think I am good at reading people, and then I find out I'm SO VERY WRONG. I think something good will finally come of my attempts at being a kind person, I am mistaken. I think I know someone, they turn out to be the complete opposite. My mother and I have been fighting constantly because she is terrified I will make the same mistakes in life that she did. I feel as if she is treating me like a child, and taking out her frustrations on me, so we constantly bicker. Today we got into a screaming match because we were both upset about Nathan being gone. It was awful. I just burst into tears, going into a panic attack. Finally my mother comes back to my room, tears in her eyes telling me how awful it is for her to watch me go through this. She sees how hard this year has been for me and how I can't seem to catch a FUCKING BREAK. I am literally pulling my own hair and sobbing about what a failure I am. When's it gonna get good again? Don't I deserve something better by now? Haven't I proved that I am a good person, even when treated badly? If I get one more kick while I'm down, I give up.
