Thank you both for responding. The article has helped a great deal. Knowing that I'm not the only one who has felt this way is of great comfort, and reading through the comments I've realised that maybe allowing myself to feel the sadness and expressing it will help. Before I was kinda fighting the feelings, and suppressing them because I felt wrong feeling them.

And 2B/-2B thank you for your insights too. You are right. My friend's support gave me the strength to get through situations I don't think I could have got through othewise, and gave me the courage to believe I could deal with the consequences of changes I had to make. What you said about the fear is, when I think about, it spot on. Thank you both.
