Family drama movie I saw probably in the 90´s in the TV. The son had some kind of an accident and had to learn everything again (like reading etc.) The mother was teaching him and probably had some sort of breakdown. Then I remember the daughter of the family who went through some rebellious phase, including drugs probably (not sure). Then I remember the whole family burying a box of the son´s stuff from his previous “normal” life.  It was quite depressing movie but I wonder what was it!
