Thanks for your replies and encouragements everyone. I feel a lot more positive and hopeful than I did this morning. Although pysically I feel as if I was battered....I suppose I was. I thought my heart was going to come through my chest with the anxiety. This is just not worth it.
After the first few replies I was actually reduced to tears. For me that tells me I'd reached my limit. My breaking point. It also shows me the power of reaching out and asking for a helping hand and realising there are people in the same boat...people who have overcome the same problem....people who answer that call.
