Sick Avocado Pest Puerto Rico white web fuzz Fungus insect

Hi. I have an avocado plant in Puerto Rico and I don`t know what is wrong with it. There is a pest on it, and it seems to make a white fuzz fluff web or hair-like structure around the leaves of my plant. Also has yellowing leaves with brown spots and white spots, holes in the leaves. I tried washing the plant with water to get the white fluff off, and while it comes off the insects just make it again. I`m at a loss as to what to do and would appreciate any help anyone can provide. I don`t want my plant to die.

Here is a second photo of my plant, any help anyone can provide would be extremely appreciated.

It's difficult to tell for sure, but it looks like a mealybug infestation. This is what they look like:

@bettydee Thank you for your response and suggestion. I'm going to try figure it out, and hopefully you're right and I can deal with the issue.
