I can't speak for others; but I would have to agree.
I used to get angry because of the medication... and my husband! I would have thoughts like: "Why do I have to take this medication if he is being such a butthead?" I loathe taking my medication, but if I don't, I have real problems. When I don't I feel angry and like I want to rage (imagine the old "Incredible Hulk Show" when Bill Bigsby changes into "The Hulk" Lou Ferrigno) I can relate.
Therapy helps. (we are now in marriage counseling) I am blessed with an excellent therapist!
I have had about five therapists (at different times within 20 years) and they are the warm fuzzy therapists... they want to know how things are and then the whole session is me complaining; I believe that just inabled me to have a pity party.
The marriage counselor has helped me the most. She says it like it is and that works for me; it may not be the best for others.
