hi raisin,
sounds like you took action and things are looking up for your son. i'm a mom too so i could really relate to your feelings about to help your son's bipolar. one word of encouragement from me- once he is put on meds that help his bipolar he will be so much better. it took some trial and error with my case but it has been well worth it. i returned to a high stressed career after getting stable and enjoyed 7 more years of working.
i'm sure your son knows you are his best advocate. hope he continues to improve.
