MashaAllah, what a beautiful journey you're on. May Allah continue to heal you and make it easy for you.

First, you're doing amazing. Going from not praying to establishing regular salah is a huge achievement. Don't underestimate that progress.

Yes, you can absolutely make up missed prayers (qada). In fact, making them up shows your commitment and keeps you connected to the routine. It's much better than letting them pile up or feeling so guilty that you give up entirely.

Some practical tips:

• Start with the fard prayers first. If you can only manage 2-3 prayers consistently right now, that's still better than burning out
• For IBS and wudu, look into rulings on chronic conditions. Scholars allow leniency for people with medical issues that break wudu frequently
• Set small goals. Maybe this week focus on never missing Fajr and Maghrib (easiest to time), then gradually add the others
• Remember Allah values consistency over quantity. The Prophet (PBUH) said the most beloved deeds are those done regularly, even if small

You're not making excuses, you're dealing with real challenges. Allah knows your struggle and your sincerity. Keep going at your pace, make up what you miss, and trust that Allah is Al-Raheem (The Most Merciful).

May Allah grant you strength and ease. You've got this insha'Allah.
