I haven’t slept normally for months

My body is exhausted, my mind is foggy, and my heart feels heavy. I wake up every morning around 5am feeling like I've been hit by a truck. I'm 30, but some days I feel like I've not lived at all. Living with PTSD has made every day a battle, I struggle to just hold on and keep going. The trauma from my past haunts me every waking moment. The memories creep into my thoughts when I least expect it, triggering anxiety and panic attacks, especially in the morning. I'm constantly on edge, waiting for the next nightmare to come to life while I’m having morning toast with coffee. Trusting people I want to get close to feels impossible, and I'm always second-guessing their intentions. It's like I'm living in a never-ending nightmare of family abuse, and there's no escape. The nights are the worst. My stepfather used sleep deprivation as a form of punishment, and I have crippling insomnia reminding me of those horrible days when I slept for two hours each night. Sleep is a luxury and my worst enemy. I toss and turn, haunted by nightmares and flashbacks that leave me drenched in sweat and gasping for air. I can't sleep for more than 3-4 hours, and even that is plagued by restlessness and fear. The exhaustion weighs me down, making it even harder to face the day ahead. I've tried therapy and medication, but it's been impossible to find the right support. It feels like I'm fighting this battle alone, with no end in sight. I can’t even sleep with someone in the same room, and I’ll never be able to share a bed with another person. The constant fatigue and sleep deprivation only make it harder to cope with my symptoms. If I could get at least a week's worth of decent sleep, I think most of my symptoms would get better. How do I break free from this?
