Last year I felt so strong in Ramadhan despite not fasting forna few years because of pregnancy and breastfeeding. I know some women are stronger and manage but I wasn't doing so well although if it was winter I probably would have.
This year I'm finding it harder but I think that's because of so many things going on and I'm mentally blocking myself.
What helps is reading the seerah and just seeing and realising the struggles of the past in all aspects of life and on all days. It just helps he love to be honest. Really encouraging.
Try to have wudhu as much as you can so in spare time you can read Qur'an.
Also when just sitting around or going to be saying Allah's name, Subhanallah, Allahu Akbar etc.
La ilaha illallah astaghfirullah as'alukal jannah wa a'oodhu bika minannaar is one of the main dhikr for Ramadhan.
Sitting between asr and maghrib and reading du'as from hizbul a'dham which is a compilation of all prayers from the Qur'an and Hadeeth and covers all aspects of life. One of my faves.
We haven't had fried food either and it does make you feel better but be true to yourself and if you feel tired then rest but you can also do dhikr whilst resting.
Donate to charity often even if it's £1 here and there I find it easy to donate to UWT online and I'd do say £5 every week or something like that.
Having kids and parenting them is ibadah in itself so in ramadhan the rewards are multiplied so we are lucky in that sense even without the praying.
Insha Allah I'll be able to act on the above myself.
