Acceptance is a killer. My son is 20 and he is on 4 types of medication.
Through the aggression period and the acceptance that I have to give him all these medications I sometimes feared for my life.
Now, full of acceptance I have learnt mainly 2 things. Aggression (even tho on medication) gets worst if:
1. his hormones rise and he longs to have sex (unfortunately or fortunately he does not get any sex

)
2. he has a new physical illness that needs to be diagnosed and solved.
For sure allergies is one that sneak up a lot.
