It takes a lot of self-awareness to learn the techniques that will help you get through a single hour, let alone a day, and the discipline to keep working at it every time your anxiety gets bad. You have to constantly practice. I stopped going to therapy and taking medication because I can't afford it, I know it would help but I don't have the income. I have to rely on things that I learned on my own. Picked up a couple breathing techniques for my panic attacks, remind myself that a flashback is simply a strong memory and I'm safe now (harder than it sounds), know that a hallucination is simply that (I'm not actually seeing or hearing these things because there's no way it can be possible), keeping a written journal of the symptoms of my depression to analyze the pattern and work on it, and I make myself count the colors and the sounds of where ever I am when I don't know if I'm awake or not. All of this is still difficult for me but it's gotten so much easier than when I first started. Doing all of this is like working a muscle and the more I work, the easier it gets to practice. These things make my life manageable, not easy, but manageable.
My advice is to look for techniques that suit you and practice them every minute of every day to help you manage. Yes, I'm worried I'll never recover. Hell, I know I'll never really recover. That doesn't mean I can't make my life worth it. I can always improve other aspects of my mental health and life in general. I just have to keep working.

Good luck.
