Stress causing relapse...

I shaved my head a little over a year ago because of all the bald spots and it just looked so bad. I had been pull free since recently. I have PTSD and i've been stressed out with college and memory problems, depression etc. I'd been resisting the urge to pull for a few weeks now pulling maybe 1 hair here and there, but today, chunks. Behind my right ear. I started pulling my hair out after the abuse i endured 4 years ago i was diagnosed with trich at the same time at PTSD.

Anyone else's trich get worse with stress or other issues like ptsd symptom relapse. These things are happening at the same time with me right now and I feel so guilty having given in to the urges... now i fear i wont be able to stop like before...
