I am depressed stressed and scared help

I’m gonna try to keep this as short as possible.

My son is 3. His father was just a one night stand and does not help me with him financially but once in a blue moon. Me and my son rent a room at his mother’s house.

My sons father was living in California to avoid child support until about two months ago cause his gf dumped him again. During that time we got too close. To the point he talked me into cuddling he felt me up we kissed and I went down on him

The next day found a crack pipe and various pills in his bag. He has a pill problem. But swore on his own son that a friend put the crack pipe into his bag

Since he has been back he has begged me to get him lyfts weed money to the point of over drafting my account and I only get SSI cause of spine surgery and stuff. He swore he was gonna pay back but as of now. I doubt it

But anyway today a box came in the mail for my sons father. We all knew it was drugs for him to use and sell. It was so obvious. He lied and said it was a purse and some lotions for family members

I didn’t like he was doing bringing illegal stuff here so I planned to save it for his mom when she got home. He kept begging his sister to get it from that fat fucking bitch (me). Then said if I open it he was gonna tell his brothers and they was gonna fuck me up.

Then he switched to it he was gonna call the cops if I opened it up. But my son has the same name as him cause he is a junior. I wouldn’t get into trouble. My son lives here his father doesnt.

Then when the sister said I was gonna give it to his mom. He said no it is dinero dinero dinero. Then said he would call the cops on her if she opened it. Then went onto start insulting me so horribly to the point I was crying

He said I fake my medical problems and I’m the bum ass mom cause he is working and getting his son pull ups tonight. Still no pull ups and he only had this job for two weeks. He also said I’m only mad cause I want his “meat” and he won’t give me sex cause he don’t want to stick it inside me. He isn’t attracted to my fat ass or anything like that. Just pure insults.

I have back the box. Hid in my room while he cane and got it. I just cried and cried. Still crying as I write this.

I was already planning to move out by New Years cause they over spoil my son so much that is delayed. But now I’m uncomfortable scared depressed and stressed I want out by December 1st or sooner

I know that I’m not gonna survive thanksgiving. I’m actually considering calling a domestic abuse shelter to take me and my son in but idk if this is even considered abuse.

And on Monday which is my bday I now plan to go see about some housing assistance and getting on some waiting lists for shelters for me and my son.

What would you all do? Any advice is appreciated. I have ptsd too btw so this whole experience has been draining and brought back nightmares from years ago.

Please help! I can’t survive this much longer
