How can I occupy my mind

J
So my SO has just told me he's going away to in February with his Dad and Brother to train for a challenge he is doing. I knew he was going before but he told me the dates and plan last night. I don't think he realised when agreeing but it covers the anniversary of when we miscarried, he doesn't like to talk or think about it which is probably why it's slipped his mind. I'm starting to worry about being on my own at such a tough time and don't know what to do to take my mind off it all, I'll be at work throughout the day but obviously at night is when your mind starts playing up and I'll be alone. Advice from you wonderful ladies is greatly appreciated 😘😘
