I'm sorry it's hard and painful, SAWE, but I am really happy that you have a T who is direct with you and is helping you face this and go through it - it means she does care for you, has your best interests in mind, and is a good T.
It sucks majorly, but it's really much much better to live in reality, in mindfulness, than in denial ... I know denial is the place of least resistance and easier to stay in, but what is most comfortable/easy is not best always for the growth and healing of heart mind and soul (it's a false easiness). But then, I know you know that .... and I know that because you have had the strength to come this far, you are not going to turn back, turn away .... you'll keep going and the strength for the journey will keep coming! You're doing well, really I think so.
Many hugs to you!
