It honestly does get easier hun, the pain never goes away entirely, and often it creeps up on you when you least expect it, but it does lessen
When I first lost Max in July I kind of went into denial I guess, I refused to talk about it to anyone (apart from Purrs Peeps who were wonderful), and just kept myself really busy. It was weird though, I was kind of on autopilot, doing the things I'd normally do, but had no recollection of doing them, just kept going day to day.
I'm still nowhere near back to normal, over 4 months have passed and the pain is still there, I still have a good old cry regularly when I need to, but it helps, and you have to let it out, and do it in your own time.
Oliver probably is still with you hun, I've certainly sensed Max on several occasions, I don't believe they ever truly leave us xxx
