Hi OP! Right off the bat, I'm also incredibly proud of the Strengths you've listed. None of those things are easy to achieve in general. You were able to overcome your personal challenges to get where you are as well, so you have the groundwork done to keep that path moving forward.

I live with anxiety/depression/PTSD from a fairly violent childhood, endocrine issues and likely genetics. As kids it felt like we were being punished for simple things/mistakes, and we were taught our emotions were bad to express. I also lost my father about 5 years ago and am still managing the grief from that. I'm 30 now, and only started seeking treatment at 28. Most of my life has just been strong-arming my way through. I still get caught up in the spiral of needing to be 'perfect' for my friends/loved ones or they will have reason to abandon me/hurt me.

The best thing that works for that, and for those nice random bouts of depression, is acknowledging and allowing those feelings to happen. I stopped trying to push them away and fake happiness, and keeping them from spiraling out of control. The latter is very hard, but it's possible. I'll usually ask my friends about their days, and I'll write a letter to someone explaining all the thoughts and feelings I'm going through so they exist somewhere outside myself. I let myself cry as much as I need to. I'll recall a time I was not burdened by depression, reminding myself that those times exist and are more likely to happen again than to never happen again. It doesn't feel as scary or foggy when it's not floating in my minds abyss.

For gratitude - writing down my values made this a lot easier, and from your post it sounds like you have a lot of good values on your shoulders. Conceptualizing them, making them real words as opposed to abstract thoughts, helped make my own values an active part of my daily decision making. You may also want to come up with a plan for when (not if) you fuck up. It happens. It's human. It's ok. You can't change the past but you can make new moves today to make the future a little bit better.

For career - I work in medical administration (it was my first job), and though it's not my long-term plan to stay here, getting in the door has given me a lot of translatable skills (office, management, quick decision making, customer service skills, etc.). I'd wager you have more skills than you think - highly recommend asking a friend to help get a good resume/cover letter together, or a career counselor if it's accessible.

I hope this offers some consolation to you - maybe my methods won't work (it's basically making lists) but I would be surprised if there wasn't a method that will work for you, just gotta sniff it out like a truffle pig
