Struggling with My Identity and Future

So for background, I legally changed my whole name when I turned 18. Now i will randomly dead name my self, not even in the sense of im talking to my self and use my old name, my brain will just Say It for no reason. This causes me to like de-attach from my new name and basically causes a mini identity crisis because my conscious is just floating around with no name attached to it. But lately, with me being in college and all, everyone keeps asking about my future and all that. So im stuck in that What do i want to do with my life who do i want to be and none of my cloths Feel like me anymore so im not comfortable in anything i wear but i cannot afford to get clothes that do feel like me. It’s making me so overwhelmed and overstimulated and i dont know how to get out of this head space and i wanna cry.
