I have a good care coordinator but that's it. I might be starting DBT soon, don't know

I don't know how long I'll be waiting for the assessment but it looks like I'm only going to be offered DBT, not individual.
I suppose I am well enough to do voluntary work but the whole thing just scares me. My eating is messy, I've not been free of self harm for long at all, I get a lot of admissions with my Eczema and mental health, my flashbacks/anxiety/dissociation/panic are all pretty bad etc.
Thanks for the replies.
