No, burnout is very normal. May your tefillos and the tefillos of others on your behalf be answered l’tova bekarov! Yeshuas Hashm kiheref ayin.

Two personal stories (rather long, sorry): Everyone in my family married late, my parents, siblings, relatives — the youngest to get married was almost thirty, the others including me almost forty, almost fifty (to people of comparable age or older)–but just because it was the family experience didn’t make it easier. It was very very hard and there were times i (I can’t speak for my siblings/relatives) did give up. One year I took a trip to EY with a friend — a tzaddeikes to put up with me–and we went to kivrei tzaddikim, davened whereever we could, and cried all the way to AMuka, all the time there, and all the time back. Did I meet my future husband there? No, not until about a year later (ten years in older-single time).
Did the tefillos and tears help? Yes.
Eventually I went to a gadol and said listen, i’m a woman, there’s no chiyuv on me to marry, i’m really feeling old and tired and discouraged, so is it ok if i stop dating already? like, if Hshm wants me to get married He can just trap me in an elevator with the right guy or something, right?
to my surprise the rav said no, you do have a chiyuv, the man can’t marry without you, etc. then he asked about the men i had seen lately and gave me some good advice, which i followed.
so about a week later, after standing my future husband up one time because he didn’t sound so excited (to my jaundiced ears) he proposed on the third date but i was so shell-shocked it didn’t really penetrate.
fast forward a few years and b”H a few children later and my older brother–a much nicer and better person than i will ever be–is still single. mid-forties. parshas chayei sara. i’m on the phone wishing my mother a good shabbos and tell her to daven hard for brother this week. i start to cry because i really remember how it felt and imagine how it is for him and my mother is shocked. i hang up with her and grab my boys’ hands and tell them we are going to practice dancing for uncle x’s wedding and we dance around and around singing ohd yeshama and crying until we fell down. then my husband gave tzedaka with him in mind.
my brother got engaged that purim.
we are not taking any credit for it but our tefillos couldn’t have hurt.
i know other people’s stories don’t really help but, try not to give up entirely. Hatzlacha!
