bumps in my mouth!

i’m an 18 year old female, i keep my hygiene maintained but the past year has been difficult. my tonsils are huge and red, my throat is always sore from this and i’m always sick! but my tonsils have plaque stones in them, some days just a little and other days the entire tonsil is covered. i can poke them out but they bleed. my mouth smells horrible after. ive began to get these huge red bumps on the back of my tongue and plaque. (i brush my teeth correctly, four times a day) i drink plenty water and my tooth brush is disposed weekly thru this. i have no idea what to do! i know i need my tonsils removed & i have an appointment in august (i just got insurance) but until then i need tips. i’m busy, im a CNA, im in college and i’m a foster mother of a 2 year old boy who’s failure to thrive, he’s a lot of work. he’s needs come before mine. PLEASE give me tips.
