I just need someone to talk to or just hear my rant. Sorry for the book.

I've had a very stressful week. I just got a new job as a dietary assistant. I've had 3 days of orientation learning about eve thing I need to know about a nursing home. It was sup overwhelming because I've never had such a serous job like this. On Tuesday my boyfriend and I were playing on going to the movies for a date (we have never been on a serious day in the 2 years we have been together) I was super excited because he wants to do something I enjoy (he doesn't like movies. Games are better he says) well the plans dropped out. I was upset about it because I got all dressed up, shaved, did my hair so that was a let down because for the past couple of days before that my mom and here boyfriend replaced and my mom was freaking out. She game into my room saying that here was cops all around our house and that there was kids running in and out of our yard. She was standing in my bed looking out the window. Then my moms boyfriend thought it would be a good idea to propose to her while he was still high. She said not because he broke her trust with bring drugs in our house, breaking her trust and she knows he probably stole to get the ring. They were fighting all week about that.... lets go back to Tuesday after that I didn't get to talk to my boyfriend for 2 days. Thursday was his day off because that's when he plays d&d (Dungeons and dragons) with his friends. I miss him you know? When I massage him saying hey he replied with yes? (I HATE when people say "what" "I'm busy" or " what do you want?" And also "yes". To me it comes off as super rude and as if I'm bothering you with my presence) my emotions skipped over sad and went to pissed off mode. I told I'd talk to him later cuz I was being a bother to him and his stupid kids game. I went to bed mad not able to talk to any of my friends about how I was feeling because half of them don't even like him because they think he's a asshole. ( I also have friends who have learning disabilities and I don't want to put that kind of negativity in there life) anyways I woke up this morning hearing a guy talking. I went up stairs to seem my moms boyfriend laying on the garage floor talking to himself. With his pants to his knees. He was laying in front of the door curled up in a ball just acting so weird. I started to freak out I didn't know what to do. My anxiety kicked I started shaking sweating the whole nine yards. I called his my mom and she told me to give him a blanket so he can sleep. I kept worrying about him. I texted my mom and told her what was going on. I ended up being him into the house so he could sleep in a bed. I gave him water, food. I can still hear him talking to himself upstairs (he's probably hasn't slept for 4 days). I feel like I have no one to talk to about how I feel about everything that is going one. It was the most shocking thing I have ever seen in my life. I'm still shaking to this moment. I'm feeling every emotion in the book right now I don't know how to deal with how I am feeling right now. I'm scared, stressed, mad, sad, overwhelmed, shocked. All I wanted to do was see my boyfriend on Tuesday because days before that were hell and now I'm talking care of a 42ish man who is on meth. I'm only 19 I shouldn't be doing this
