vomiting, non-interactive, lazy, keeps fluffy

I have a slaty headed parakeet at home for 8 years now and it is not keeping well. It use to be very interactive and all the time talking. Now it has become less interactive over a period of 2 months. He seems very depressed, vomits every other day, is lazy, doesnt respond back to me much and wants to sleep in my lap all day while resting on both legs. I put him in his cage every night and am worried about him as I feel he might get tired while standing on one foot.

Please tell me what should I do.

Thanks
Dhanak
