Dig around and see what you can find with community resources and county resources. All the support groups I found were free to attend and didn't need insurance to cover the cost. Walk-in counselors may not be licensed and may just be grad students, but still a possibility. Not sure.

I definitely think you should pick up . your guitars again! Music heals. It always heals. Esp. when you play an instrument. Doesn't matter what level proficiency you are either. I just know from my own experience, when I was recovering from my TBI, my drum circle weekly sessions definitely contributed to my healing journey. Thank you for your compassion, too. That means a lot.

People in the music biz can be narcissistic and arrogant. Sorry to hear that your partner wasn't supportive of you while you struggled with those hospital stays and everything. You deserve better!

I dated a double bass player right before my TBI accident and the douche canoe dumped me while I was recovering in the hospital. I still run into him when he comes through town to play a gig (we know mutual people) and he's still a douche canoe. Just 20 years older. But he's afraid of me now that I see through his facade and have very rigid boundaries with him. Narcissists hate it when their victims "grey rock" them.

Give your guitar a dust-off and see how you feel playing it again. And definitely check out the drum circle scene there in your city. I have a feeling you'd really enjoy it and feel its healing effects.
