A week ago i was at a point where ending things wouldnt have killled me but things didnt end and i jumped back in to things knowing that it would never work, now i find myself at a point where I have nothing to look forward to at all, not college(dont know whats going to happen with that), not friends (don’t have them), not school (i’m an utter failure), not home (i’m an utter failure), not the future (everytime i’ve tried to change i havent), not life (there is not one single time in my life i have made a positive difference for anyone). Not anything. I wish it could all end. I wish God would just take me now. Why hasn’t he? I hate it I hate everything I have ever done. I hate everything I am made of. God please take me now, I beg this of you.
I'll never understand myself. :'(
And I’ll never understand why I’m still here, I don’t deserve to be and by NO means do I need to be. The world would be not a single bit different without me. Scratch that, it would be better off without me.
I like how fuck is in all three tumblrclouds I made. Fuck that. haha
Sacrifices must be made. :)
Today, I was playing Farmville all day, and I was really into the game. I was getting phone calls all day, but I kept ignoring them cause I was making so much Farm Money. Come to find out it was my son’s school. He fell off the jungle gym and broke his arm. FML
When a major turning point in your life happens and you know it, you begin to break down your entire life causing a break down in yourself.

Today, I found out I’m sterile. My wife and I have three kids: 14, 11, and 4. FML
i just dont get how i can completely innocently ask a question then get told to chill when in no sense at all am i freaking out then be gotten mad at then finally get to the point where its good again and having reallly good conversation actually then when i try to understand something to make that something better i get a pie to the face like whoa curveball? definitely didnt see that coming? like i though understanding how to do things better would make things better overall but for some reason i guess im supposed to be left in the dark about things? i dont understand how this happens at all like today has definitely been the rollercoasteriest day of my life like i am utterly confused at the moment?
