Dear Reshma Irshad,
I know you didn't address me personally, but I felt it in my heart to tell you these words, because I'm going through the same thing myself for nearly 4 years now. Imagine: I'm in my 20'es, I'm psychically and physically healthy (Alhamdulilah), I've finished university, and I'm struggling to earn my living! My mom has to sustain me (like your daughter with you). I don't know about other countries, but in my country there's is a deep crisis and a high unemployment rate. So, I understand what you're going through. But there are some things I do which I'd recommend you do as well: 1) everytime I get depressed and can't sleep, I open this forum, or beloved brother Joseph's articles (especially the ones regarding "God's love and mercy", and "the trials") . 2) At the end of each salat, open your heart to God, and pray to him to help you. Here's a dua which I like very much: "Allahumma la sahla 'ila ma ja'altahu sahlan wa Anta taj'alul-hazna, 'itha shitta sahlan" (Oh my God, there is no easy except what you make easy, and you make the difficult easy if you wish"). 3) Everytime you feel overwhelmed, remind yourself that God hasn't forgotten about you - He's seeing you, He knows your situation, and He will help you in the appointed time, just trust Him
because "And there is no creature on earth for whom Allah hasn't provided for, and He knows its place of dwelling and place of storage. All is in a clear register." (Hud, 6).
Do the best you can to look for a job, strive to stay away from what he has forbidden, and put your trust in Him my sister, for He never lets down the ones who trust Him
Your sister,
Seraphina
