Hi there, thanks for asking. feeling grief is a natural experience in life, especially for parents. If it takes more than 6 months it does not assumed as a normal grief. As you mentioned it is a mixture of depressive and anxiety
can come from preoccupation about the past and anxiety can come from unclear future if you feel so. It could be managed with a medication, talk sessions or both. If it is left untreated, it can cause more impaired days of your life. Taking help from your family and social network and being more engaged with them can lead to healing sooner than expected as well. You may ask your doctor to begin the therapy upon your preference. I wish you the best health.
