I can understand the discomfort you are going through.
Take a handful of water or a shallow bowl of water and try blinking inside the water. If the FB-foreign body( insect / a piece of it) is lying loose in the superficial layers of conjunctiva
,with a couple of blinks it will come out.
Ask someone to see your eye with a torch light beam focused under the upper lid ,while they pull it up and you look towards your nose tip.
If you find something,which didn't come out with washing/ blinking, then it must be clinging a little deeper to manipulate and can only be removed under a slit lamp microscope by an ophthalmologist/ optometrist. Don't manipulate your eye too much, to avoid secondary Corneal abrasions due to the FB.
