Welcome to Beyond Blue ..... but I must say, I am so sorry to read about what has brought you here; the loss of your Mum.
I too lost my Mum, 8 years ago now, also to cancer. She was 69 years old and my best, best friend. And just lately, when I see certain ads or shows on TV, that make me think of my Mum, the tears can still flow, and my heart becomes heavy again. I miss her so very much.
The one thing I do know though, is that no one and nothing can ever take the memory of her away from me. She is forever in my heart, and is a part of my soul.
Two months isn't very long when it comes to losing someone so close to you. It's gonna take quite some time to learn to adjust to life without your Mum. Just remember to be gentle with yourself, and don't try to 'be brave' just because you think you 'should'. Grief hurts and is, in my opinion, the heaviest of all emotions, because with it comes every other heavy emotion; anger, sadness, confusion ..... all of it. It's all there and can feel all consuming. Just take it minute by minute.
And remember, you can come back here as much as you like and need to. ((((hugs)))) Take care. I'll be thinking of you. xo
