help ??? I think I am addicted to Benadryl!!!

Ladies i started taking Benadryl when I was pregnant to fall asleep because my insomnia was ridiculous. We my son is not 8 months old and I still take them everyday , at this point sometimes I even take two because it no longer gets me sleepy. Idk but I am starting to think I am addicted because I can't go one day with out taking one😩 also i am starting to think that it's having an effect on me, like I am really starting to think that it makes me extremely tired the next day , it's giving me depression and I am becoming anti-social. Is this just in my head? Any other mommies experienced this on the past? I am afraid to speak to a doctor because I don't want them to ever think I am unstable to have my baby boy with Me. Thanks god ive never had any negative thoughts like that
