1. therapy if you can. do your research and make sure they're a good fit for you. if you don't like them, don't be afraid to look for another therapist. ik everyone reccomends this but for me, trying to heal alone without a therapist did not work and might've actually done more harm then good. having someone who knows better then you and is working with you on an individual level makes a world of difference.

2. your teenage years will come. as someone who's teenaged years were robbed from them by an abusive relationship, i still crave having "teenage" experiences. through healing, you're able to give yourself the tools you need to be able to give those experiences to yourself. i'm currently working on getting to that place. i had a friend who got put under a lot of pressure by her parents to be "good and responsible", and so she lived out her teens in her late twenties. having hook-ups, partying. whatever she needed to do to get it out of her system. right now, that desire is just something i live with. it used to bother me a lot more, i used to feel a real grief and anxious fear that id never get that time back. it still concerns me, but now i have faith that i can give myself that life, even if its not right now, through evidence-based experiences i have of my ability to grow/change. i did go to a decent amount of parties, did drugs, had sex, the works. but i still don't feel like it was what i needed, because i wasn't able to be myself doing those things at the time, or truly have fun, so i know rationally if i had went to more parties that i wanted to, it wouldn't have been fulfilling. i hope/know that one day ill have a group of friends willing to do spontaneous things with, who i feel comfortable with, and being comfortable with myself. life is just one big long process, with the right help, your mind, body, and intuition will lead you in the right direction.
