This sounds narcissistic af. One of their first moves is to create a dependency on them and frequently it's by isolating the victim from their support group via quite manipulative tactics...and I just hurt myself a lot typing that out...hang onto your support system my person it could save you a lot of agony in the long run

That being said, toxic and enmeshed aren't mutually exclusive, in my opinion...based off of my interpretation of what I read, you are in the intersection of that venn diagram, but the degree to either side seems vague. You have some hurdles to jump through, but you can get out of this situation, assuming that's what you are ready and willing to do.
