<human>: A little background story: i was born as a mistake. My mother ran off with me to ohio when i was 1 or 2, but left me with her then husband (who i thought was my dad) when i was 3 or 4, to "find a place to live"... So weeks went by and she didnt return, so i ended up going back to Georgia to live with my mom's mom and my two aunts. My dad eventually found out where i was and came to get me. So at 5 years old, i met my dad for my first time. And man was i so confused.. I remember it to this day... 

All my life growing up, he cared for me, and did everything he could to make sure i had what i needed. All those night shifts as a cook.. Its crazy. 

My mom comes back into my life in the 6th grade and im ecstatic. Ive only always fantasized about her all my life, and here she is!!! So by 8th grade, im living with my mom, a few states away from my dad. 

That is when my dad starts to go down hill.

He somehow lost his job, pissed off pretty much all his family of which he was living with at one point, but he's so stubborn and bitter, well, the relationships are ruined. 

Which my dad can be pretty mean and horribly stubborn. Especially when drunk.

He's 50 now. He has been homeless for a little less than a year, and it stresses the hell out of me. Thankfully he has food stamps and an obama phone, so i can keep in touch with him. 

Im really bad at keeping in touch with him though, and i feel horrible about it. Its just so damn depressing. My mind just chooses to block it out! 
I'm the only thing he has left in life, and i can't even call him as nearly often as i should.

Its such a mental burden. I wish i just didnt have it.

Btw im 20 now.

Give me the gist of the text in a nutshell
<bot>: My dad has been homeless for about a year, and it's a very deep worry. I'm 20, currently without a car, and there's nothing i feel like i can do.
