Terrified

So today, my dog hasn't been acting normal. He can't sit still, and is panting really hard. He has had these lumps on his body for a long time now. We knew it wasn't good, but we just cant afford to take him to the vet. Today is the day; he has an appointment for the vet at 5 PM. I know we can't afford for any medicine or anything like that, so right now, might be the last time I see my dog again. =( I am praying he is going to be okay, but it might be his time to go. I hope to see you again Astro! <3
