Feeling sad and empty

Hi, this is more related to February’s work but I’m really struggling with feeling many feelings in my body. I have identified a feeling of sadness and/or emptiness, but I feel absolutely nothing in my body. I can’t for the life of me come up with a thought that is causing this. I know that I’ve had a week long migraine/bad headache, and I’m thinking that maybe it’s just the sedative state from that?
However, there are many different feelings that I can’t feel in my body, ever. Things like excitement or anxiety, which are quite “strong” feelings I can feel, but the more laid back ones such as sad or content doesn’t seem to bring any bodily feelings with them. Do you have any suggestions?
