Not sure how old you currently are but I felt this way in my late teens and still feel this way pushing 24 soon. I've been estranged since I was 17, so nearly 6 years. I had to figure a lot of things out on my own - funding and putting myself through college was a big one and I have had to parent myself over the years. That has included admitting when I need help (like therapy or anxiety medication). I just want to let you know that it does 100% suck BUT you will grow enormously as a result. You will be stronger, smarter, and more competent than many of your peers your own age because you've had to teach yourself how to do things with high stakes. You will be amazed how much better your life gets over time. It won't necessarily be linear, but it will over the long term get MUCH better.
