Ever just feel so ready for a breakdown 😭😭😭

I am so full of panic, worry, stress, anxiety, nausea, hurt, and fear, I feel like I'm just ready to breakdown. I am 35 weeks pregnant living at home with my parents and have a 4 year old son. Got into a relationship with a 3rd cousin, didn't know that right away, but didn't stop us anyway, we had never met before. But anyway, family found out, and forbid it, but it didn't stop me, then I got pregnant and have been so scared up to now to tell anyone, including him. I haven't spoke to him since I was like 12 weeks. I have done nothing but completely run from all responsibility, now I have no money, no where to go, it's the weekend so nothing much I can do. And I NEED to leave home. My son has a place to go until Monday, his granny has asked to have him two nights. But looks like I'll be stuck walking the streets, as I have wrote my family a letter letting them know of this. I've tried swallowing my pride and contacting friends. And even my friends in already speaking to. And seems that this one day I'm reaching out and need someone, no one is answering there phones 😭😭😭😭😭
