Skin picking - advice

I'm a 20 year old university student, who, like most skin pickers, has completely clear skin when I don't touch it. I am one of the lucky students that doesn't get spots, yet as a perfectionist, I always try to find flaws in myself. This has led to me HATING any sort of bump on my skin. I find myself staring at my skin in the mirror and, in a desperate attempt to get rid of any clogged pore, I squeeze and pick. This leaves me with scabs and red marks for days. I've tried many ways to stop doing this. I've seen a cognitive therapist, I've spoken out about it to my friends and boyfriend. However, whenever I catch a moment alone, I always find myself picking. I'm desperate to find new ways to stop doing such a self-destructive thing. Last night was particularly bad for me, resulting in me not wanting to leave my room. I've now asked my mum to book me in for regular deep cleansing facials - maybe if I let someone else pick my skin for me, I won't get the urge to do it myself. Does anyone have any advice for me? I am a really strong willed person, but when it comes to picking my skin, I just can't help myself.
