You've got 80 hours over 1,5 years - which, by all standards, is not an awful lot. Presumably at least 45 of those were your training which is done in a controlled environment where you've got someone overseeing you even for the solo flights. Which leaves you with about 30 hours as a licensed PIC. It's absolutely normal not to feel completely at ease with this number of hours, especially if you only fly on a semi-regular basis. Keep pushing and you will certainly become a lot more confident and build a lot more routine with experience.
