Should I go seek help...?

Someone please read...

I don’t know if I should go to a therapist or not... recently my boyfriends brother passed at the age of 18... same age as me. He was alive for 5 days but machines kept him alive... he was basically in a medical induced coma. I watched him slowly pass for 3 days when the family finally decided the right decision was to let him go. Anyways the whole experience has been awful and traumatizing and I just don’t know how to feel. Now a month later I thought I was about to lose my 92 year old grandfather and now he’s just in hospice... I’m basically reliving everything over again... just watching someone die! I don’t know how to feel I’m so so sooo depressed but I’m also happy bc I have my boyfriend and family. My anxiety has also gotten 10x worse and I really don’t know what to do. Should I go see someone? Like a therapist? Someone please help... I’ve gone to people before but they never help us there something else I could try? I mean I’m obviously still getting over everything but I feel lost and hopeless...
