Then reach out to other people.
I'm not in your shoes, I can't tell you what to do next,
But there's no way it's impossible for you to get help.
I know it's not impossible for me to get help. But at this point in my life going through all the roadblocks to get to that help is going to do a number of things, all of which are negative.
Then honestly, that's on you.
Your decision not to get help is completely a you thing.
One, it'll uproot my life, something that has happened more than 11 times, (that's the number of times I've moved in my life. Not counting surviving a divorce, losing friends, getting lice a number of times, and the night the police had to be called back when I was maybe 5-6.
Perhaps for the better. The literal definition of 'help' is "make it easier for (someone) to do something by offering one's services or resources."
Two. It'll probably destroy my already shaky relationship with my mom. Permanently. And I am not ready for that to happen.
If your mother doesn't want you to get mental health support, maybe that's another thing you could seek help for.
Three. It would change everything I know about myself,
….
How??
Four. It will involve going back into some nasty emotional stuff I survived as a kid and teen, a lot of which I only know about thanks to my mom's blog, leading me to believe I have suppressed memories.
Again with this online stuff. I mean this in a helpful way: "leading me to believe" does not equal "I have."
And if you decided you didn't want to go back to those nasty things, a professional can't make you. They can only suggest.
Five, the fight and push to get help will probably hurt me more than it will ever help me, especially at this moment in my life.
Overall, as of right this instant, it's emotionally less terrifying and potentially damaging to wait till I'm a legal adult to go look for therapy.
Nobody said you couldn't wait. If that works for you, wait.
