I am so sorry to hear about your mom - I wish there was something I can do to help. I know it's much easier said then done but for your own comfort try not to worry about what it could be. Take a look at the auxiliary session on worry. This session has some worry stopping techniques that may help you.
I am also sorry to hear about your relationship. Break ups are hard. While going through them it can seem like the end of the world. But you can come out of this stronger then ever. You can learn and grow from this experience. It may not seem like it now but there is a purpose to all this hurt you are going through. One day you will be able to look back at this and see. In the mean time we are here to help you. Post as often as you will like and we will listen - know you're not alone.
You can get through this. Where can you find strength and support. What memories can you draw upon. Who can you turn to? What can you focus on?
On friday i learned that my mum may have cancer. They have said that it could either be a bleeding ulcer or cancer. Me being me i cannot focus on it could be a bleeding ulcer all i can think about is my mum may have cancer and i may loose her. Then to top it off my relationship has broken down beyond repair!!
This really is the final set back i cam take, no matter what has happened in my life i have always got back up and carried on, this time i just cant its too hard.
