I don’t think I’ll ever get over losing my dog

My dog died two months ago and it still doesn’t feel real. I’ve had him since I was 4 and I’m 18 now so basically my whole childhood had him in it. He was there for everything: my first day of school, my first breakup, every time I cried in my room and didn’t want to talk to anyone. He’d just curl up next to me like he knew exactly how I felt. He got sick really fast. One week he was fine the next he couldn’t even stand up without shaking. We took him to the vet and they said there wasn’t much we could do. I thought I’d have more time. I kept thinking okay maybe we’ll get one more summer together but I didn’t. The day we put him down I held him the whole time. He looked at me the same way he always did like I was his whole world. I tried so hard not to cry until it was over but when he was gone I just broke. I felt like someone ripped a part of me out. I still expect to hear his paws on the floor when I get home and I still look for him when I drop food on the ground. I don’t know if I’ll ever stop missing him. I know this all might sound dumb and childish but to me he wasn’t just a dog he was my best friend and I hate that the world just keeps going like nothing happened.. My friends and family want to get me a new dog but it just isn't the same, they don't get it at all. Any advice on what to do? How to get over this easier or will the time do it's job and I just have to bear with it..
