Thanks for sharing your concern.
you have bit your tongue accidentally,therefore it has got swollen and hurts.
Do not worry ,this will subside once it heals.As these lesions on tongue and mouth takes little more time to heal.
Regarding, your other symptoms like swollen eyes and discharge,it could be due to chronic sinusitis
or could be a viral infection too.
In my view please meet your physician once in his regard and take suitable medication.This should help.
Meanwhile do warm saline rinses and also avoid hot and spicy food until your tongue gets back to normal.
Hope it helps.
