Wa `alaykum as-Salamu wa Rahmatullahi wa Barakatuh.
Once you have done what you can according to the circumstances, you are in, and the challenges you have, you are excused.
One of the principles of the Qur’an is that Allah does not burden us with duties we cannot fulfill. He has not imposed hardships on us.
Therefore, if you have challenges or conditions that are making it hard for you to keep washing everytime, then all you need to do is to wash yourself prior to ablutions, as close to the Salah as possible, and then forget about any discharge that occurs afterwards during the Prayer.
Almighty Allah knows best.
