I'm not a psychologist so this comment is just random text that accidentally might help.

Journaling, self-reflection and professional help are a good start. Journal your daily life. Triggers, foods, challenges you set, what worked, what failed. Be more forgiving of yourself as you grow. Each failure is a learning experience. Try again. Review patterns as you notice them.

If you don't want professional help, then understand anxiety is often "too much potential future" and/or "too much recycled past" and not enough "actual now". You need to gradually build up resistance and resilience to your fears/anxiety.

Look for clinical psychologists like Jordan Peterson etc. he's posted a lot on youtube about anxiety etc. Learned helplessness and CPTSD are also some other possible things to be aware of when examining anxiety.

The problem with doing it alone is the increased number of blind alleys you will waste time in. As well as prolonging anything you don't notice. But you have your reasons - they are what they are.

Recruit allies to help where possible. Self-help does not mean you do it alone.
