Help, what is this?

[Elysee]

Dear Lucy,

thanks for you calming words. You were right. She had a little infection of her vein after her doctor taking some blood last friday. So that was the lump in her arm. It is already got smaller. Oh Goodness, I was so scared again... It feels like permanent fear is the only feeling I am able to have since weeks. I know it will get better and I am really not showing her my fear and tell her every day that she will be ok. I can't even think about loosing her. My father, sister and me would loose our sunshine
