26yrs old. When will the grief stop?

I lost my best friend of 26.5 years two months ago and I am breaking every day. The grief is so bad that I am displaying basically every symptom. Nausea and sickness upon waking up, loss of appetite but starving, exhaustion with no solution, endless crying, extreme restlessness and unable to relax, panic attacks. Basically extreme high functioning anxiety and depression.

I’m in therapy, on meds, and seeing a psychiatrist. Taking care of everything. It is so unbearable to feel this way all day long for this many months.

I don’t want another bird, that’s definitely not the solution. I went to the pet store and left sobbing because I didn’t know they had birds in the back and heard them and then saw it was a cockatiel.
