Have had six sessions of counselling. Diagnosed with PTSD, cPTSD, anxiety and depression. Abused emotionally throughout childhood and a sexual incident also.
Opening up helped in some ways, but you have to click with the counsellor or you'll never feel comfortable enough to express. I'm not going to lie, I found it really difficult, my generic subconscious stance is to not trust women and be shit scared of men.
My problem was the counsellor left due to personal issues and I've not been seen since, over two years now. Dredging up the raw emotions that we hide in our subconscious, always there lurking but our subconscious protecting us. For me, it's been too much since. Flashbacks, triggering, self-harm, insomnia, the works. I saw a photo earlier today and it triggered me instantly, the problems start when you're halfway in and raw, hurtful, fearful memories and emotions are constantly swirling around your head.
Short answer? Yeah, but only if you feel strong enough to do so, and be able to see the same counsellor throughout. You need to be open if you cannot click either and ask for a different therapist. Sorry for diverging.
