Without knowing your dx or what state you live in I can only offer some general ideas.
I have MDD, PTSD, BPD and traits on the autism spectrum. These are some of the resources and services I found helpful.
DBT Dialectical Behavioural Therapy. Check your local public mental health service for access.
BPD Australia Foundation is a good resource. You can pay fee for service which is at a discounted price compared to private. Or you can exchange time volunteering or mentoring for the services offered. Their forums are very helpful. So are the face to face support groups and events and conferences they promote.
The clinical guidelines released on treatment for BPD and other personality disorder guidelines can educate you on what works and how to access it. All the current therapies are listed along with how effective they are.
Therapies require a time and attendance commitment from providers and clients to be effective.
Generally at least a year, sometimes several years and repeats of programs are needed.Trust must be built to make change. Group work is hard, sometimes provoking and challenging. Sometimes repetitive and boring. Sometimes triggering and painful. But oh so worth it for the skills and strategies learned.
A group of people exist that has lots to offer. They share a lived experience of your dx. They are your peers. All on different parts of the journey you are walking. Best of resources to reality check with, vent to, ask questions of and to support, encourage and mentor each other. No money involved time and tolerance is the currency exchanged.
On a personal note. Huge hugs it's hard going juggling symptoms and being expected to keep up with life goals. You are young. This is a good thing. The earlier you find and enter suitable therapy the better. It is alright to take the time to learn good coping skills. If your chosen therapy has a time and place commitment you can apply to be exempt from New start to attend. Your mental health is priority number one. Looking after it pays the best dividends long term.
There are no one size fits all approach. You have every right to ask questions and plot your own course. You have every right to be here. Difference is not less just different.
I did things differently. It meant I went up a few dead end tracks before locating a path suitable for me. I took longer but I got to where and what I wanted.I am broken but I am also loved, valued and useful. I rarely choose to answer my phone too !!!
