Is it complaining against Allah to share my struggles?

Complaining to Allah vs. complaining about Allah

Scholars separate two things. Complaining to Allah, pouring your heart out in dua, is worship. Complaining about Allah, as if He wronged you, is what a believer avoids. When the Prophet Ya'qub (Jacob) lost his son Yusuf, he said:

His grief was deep and lasted years, yet the Quran honors his patience. Patience (sabr) and tears can live in the same heart.

Talking about pain isn't a lack of patience

When Aisha had a headache and said "Oh, my head!", the Prophet ﷺ answered that he should rather be the one saying "Oh, my head!" (Sahih al-Bukhari 5666). He spoke about his own pain openly. Describing symptoms to a doctor, anxiety to a therapist or a hard week to a friend is the same kind of honesty.

What to avoid is speech that blames Allah or calls Him unjust. If anger at Allah is part of what you're feeling, you're not alone. See Is it a sin to feel angry at Allah?

Sharing wisely

• Choose the right people: a spouse, a trusted friend, an imam, a counselor or a doctor.
• Talk about your feelings, not other people's faults: you can say "things at home are hurting me" without exposing someone's private sins. See Is it backbiting to complain about someone online?
• Look for support, not just venting: sharing helps most when it leads to comfort or a next step.
• Be careful with public posts: social media often brings judgment instead of help.

Bring it to Allah too

You don't have to choose between telling people and telling Allah. Do both. Talk to Him in your own words and in your own language, as long and as honestly as you need. When hard news comes, Muslims say "Inna lillahi wa inna ilayhi raji'un." See What do I say when I hear bad news as a Muslim?

The Prophet ﷺ also said that no sorrow, sadness, hurt or distress reaches a Muslim, even the prick of a thorn, without Allah wiping away some of their sins because of it (Sahih al-Bukhari 5641). Your pain is seen, whether you speak about it or not.
