is my plant doomed

i have ittle white things inthe soil of my plant , is it good for the bin or is it worth keeping .

Are the white things spongy? It could be Perlite. Did you make the soil up yourself?

It's perlite. Comes in the soil.
If it's not perlite, the reason I'm wrong is that you have given no useful information about the 'things' other than that they are 'ittle' and 'white'. Perhaps they are grains of rice. Or hummingbird eggs. Or very small rocks (which apparently float, by the way, ask Terry Jones aka Sir Bedevere).
You really need to do some basic reading.

They could even be marshmallows.

Lucky sod :)

they are little white insects ????? they crawl about and in the soil

get a no pest strip and repot your plants w/new soil

These are either fungus gnats or white flies. Shake the plants and check to see if these little bugs fly up and the down very quickly, look close on the leaves for little skinny white bugs that will not appear to look like anything. If you see these then you have white flies. No pest strips kill a lot of them but if they have laid eggs then they will re-appear. Get safer soap and spray when light are off, under leaves and on top. You may have to do this a few times. Once bugs are gone, spray plants with water.
Like said above, some bugs will live in the soil. If a small grow-few plants, cover soil.
