like @Glisten said, there is no "right" or "wrong" way to feel about anything.... you are entitled to feel anything or even nothing.
if you don't feel "happy" with your successes that is valid response...maybe you are able to see what you have achieved...day by day, step by step....making your best efforts this past week....and give yourself a little pat on the back or even a big hug.
you are worthy of all of it and we are here celebrating and supporting you on this journey.
i know for myself...it IS vey tiring to put in such effort for yourself...constantly pushing back against addictions and habits that want to pull you down.
make sure you do what you need to do... to care for yourself...and to get good rest.
