One bad thing after another!

Anyone else feel like things just can't get worse? I have just finished recovering from an ectopic which was discovered at 8 wks after we though I had miscarried. I had the metho shot and was very sick but emotionally was dealing with it quite well. Finally got my period August 2 and starting to feel like myself again these last few weeks. Then on Tuesday I found out that my dog of 14 years has cancer and was given 1-4 months to live. This has been devastating for me as he is so important to me and has been so healthy up until this point. I feel like I can't move past it, the grief is too much. Not knowing how much time he has left is so hard but knowing he's going to be gone is worse! I'm trying to be okay as I'm sick of being the sad person but I'm feeling lost. Anyone else been through something like this and how did you get through it?
