Should i be as mad as i am?

My boyfriend and i lost our baby this week and im in the process of miscarrying and i finally got my nausea under control so i can actually be a functional human being for once. Today i asked him if we could do something with our daughter and go to the mall to return some gifts that i got as doubles he said yes, he also said he would take me with him to his friends house for a bit so i wont be alone. (Ive sobbed to him many times because i cannot handle being alone right now im severely depressed and i cry 24/7 without company to keep my mind off of everything) well he picks us up and spends about 3 hours with us (he just took us to see his mom) he told me we could go shopping before he works tomorrow but i told him we couldnt because i have my d&c scheduled. So he drops me and our daughter off at home and leaves for his friends without us. I cried before he left and told him i didnt want to be alone and that this is his only day off and id like to see him. I barely see him all week because of his work schedule and every day hes off he spends only a small portion of the day with us then leaves to see his friends or his mom. Dont get me wrong i want him to have a social life and to see his family but this is an every day thing now. Everytime he has a day off we get put last on his list because "he has other shit to do" im just baffled..im uncomfortable being in my house i cant explain the feeling but after i lost the baby i fele overwhelmed in my own house. No matter which room im in i feel weird and i end up bawling my eyes out. Do i have a right to be upset or is it just my hormones making me act silly?

Ill also add that we dont live together. So its not like i see him whenever hes off work. He just goes straight home.
