Friends in the Honeymoon Phase

Not sure if I am overthinking things but I feel like my friends relationships are making me question my own.

Only for them they are still in that honeymoon phase. They have only been together less than two years and don't live together.

My boyfriend and I have been together over 5 years and are living together. And we are going through a really rough patch with his depression. This had lead him to barely want to show any love or affection and we never go out and do things and he is hardly ever happy.

Seeing my friends all happy and loved up and posting photos of themselves all cute and coupled up in the sun and at festivals is making me feel really awful about my own relationship. I am happy for them don't get me wrong! But I am envious and feel like I shouldn't be. But I really miss those happy blissful days full of love.

Has anyone else come across this? Even not so extreme as a partner with depression but just feeling like you have lost that initial honeymoon phase playfulness while everyone around you rubs it in youlr face? (Without meaning to but they do)
