Hi Waseem~
I am so sorry to hear that you are struggling so much - especially since you've got two little ones to deal with! I was diagnosed at age 25 and I have a two year old and another on the way, so I completely understand the difficulties you are facing. It can be really scary to think about how to be the best parent you can when you are also dealing with a chronic condition.
However, it's also really important to remember that RA is a chronic condition - which means there isn't really a "final stage." Instead, RA is something that you will (unfortunately) have to manage for the rest of your life, and there will be a lot of ups and downs. It sounds like you are having a downturn - where you are dealing with a lot more pain and the medication isn't working as well as it perhaps once was. That means it is probably time to go talk to your rheumatologist about changing your treatment plan. Sometimes, for unknown reasons, medications that once worked simply stop working. The ever-changing nature of RA can be really frustrating, but luckily there are lots of good options for medications today so hopefully you and your rheumatologist can identify one that will get you more improvement in your symptoms than you have now.
In the meantime, remember that we are here to support you! In particular I understand the struggles of dealing with parenthood and RA at the same time - and I am always happy to chat about it or even just listen if you need to talk to someone who understands.
Best of luck to you! Hang in there!
