There are lots of possible outcomes. Below is an example of how life could be different. Every person is unique and their journey is unique. This is given as an indication of what is possible.

You are calmer and more authentic in all aspects of your life.

You make sure your morning routines actually happen:
You wake up in the morning and check in with yourself first: "What do I need? How is my energy?"
If you need a quiet morning to regulate, you take this time for yourself with no guilt.

You smile as you watch your significant other sleeping:
You had no idea it would be possible to have such a loving, respectful and intimate relationship with another human being.

You hear your children wake up and you feel joy:
The sounds of them starting their day melt your heart and you take time to enjoy breakfast together.

You honour your sensory needs:
You treat your nervous system signals as valid information even when it is not ideal for others,
rather than pushing through or seeing them as character flaws to overcome.

You eat healthy things your body needs:
With no concern or restriction or binging. You love respecting what your body needs.

You have regular movement routines that support your well being:
Exercise is no longer a chore or just absent. You make time to look after yourself.

Your decision-making feels so much clearer and easier:
A friend texts asking for a favour. You notice how you feel (already overstimulated from a busy day yesterday)
and say "I can't today. I could help on Thursday."

You hold your work boundaries:
A colleague's poor planning doesn't become your emergency.
You say "I'm focused on X today" without the need to over explain. 

Your finances are in order:
You understand your income, expenditure, savings, investments
and make plans for a healthy future for you and your family.

You cherish time with friends:
You are able to have deep and fulfilling friendships without getting drained,
honouring your needs while enjoying the company of others.

Conflict doesn't feel like you are being ripped apart:
When someone is disappointed with you, it's uncomfortable... and survivable.
You can sit with "They're upset AND I didn't do anything wrong" without your sense of self collapsing.

Your evening has actual downtime:
You are not squeezing in "just one more thing" for someone because you couldn't say no. 
Instead there is time to stim, engage in your special interests and unmask fully because you have protected that time
as non-negotiable rather than something that only happens when you have taken care of everyone else first.

You see your place in the bigger picture of life:
Whatever your faith, spirituality or religion, you are connected with how your life impacts others,
what you can influence and what you cannot. You use your precious energy wisely.

Your internal experience is probably the biggest shift:
Maybe most importantly, there is less background noise of "Am I enough? Am I doing enough?
Are they upset with me? Did I mess up? What do they need from me?"
Your nervous system is no longer in perpetual fawn mode, scanning for threats. 
There is space for your own thoughts, preferences and existence to just...be.

It is not that every day is perfect or easy. Neurodivergent life still has it's challenges. But the challenges are real challenges, rather than compounded layers of sacrificing yourself to manage everyone else's comfort.

You are finally free...
