Consider activities that broaden your perspective, e.g. reading a biography or travel somewhere.

Consider journaling deeply about areas that trouble you, whether recent or distant past. Also consider journaling in detail about the best possible outcome for yourself. Forcing yourself to organize thoughts in writing can help understand confusing situations.

If therapist isn't working, find another one. It's totally normal to try several.

Best of luck and good on you asking for help.
