It's tough at such an early age. But the time is right for advanced treatments and I endorse the use of biologics that someone else has mentioned here. I've been on them for a few years and I highly recommend them.
I feel for you but have nothing much to add to what is already said... except to remind you to be gentle with yourself and don't add rage and resentment for this disease to your already existing pain and difficulties. Nothing is gained by it and it will only make you feel worse.
So let it be. Treat tourself and your body with respect and take the care of it it demands of you. Rest when you must. Exercise if you can. But avoid the things that will give you more pain.
And be patient with your friends and family who may not undertsand what is going on. If they cannot see visible evidence of your suffering, it is often very hard for loved-ones to get it. Try not to resent them. Let them 'not understand' but gently, over and over if necessary, remind them, and go about your business doing whatever you need to do to look after yourself without concern for what they want from you.

There IS a bright side, though not many people will acknowledge it.
It teaches you to handle pain with humour, to not take yourself too seriously, to learn patience in suffering that helps you relate to the pain of others, even though it may be quite different from yours.
And when life gives you something that slows you down, allow it to slow you down. Living a life at a reduced pace brings its own pelasures, you just have to find out what they are.
You also wrote: "Really I'm just looking for some reassurance that it does get better for us RA sufferers."
My unequivocal answer to that is: It does – in more ways than you can imagine.
Remember to love yourself through this.
