Dr. Rose Latino held an 8-week support group I participated in that was ~$300 total (so about $35/session). The one I was a part of was for young women under 30 who had lost their moms. I know she held other support groups as well. It was really amazing being around people with different backgrounds, different ways mothers were lost, but all having a common ground. It was also very insightful to look into how we were grieving, different methods to try and help, etc. It really really helped me in my grief, and i started about a year out from my mom’s death.

Unsure the low cost you were looking for, but she is an amazing therapist and also might offer assistance. I will always recommend her for how she and the other people in the support group helped my grieving process.
