Struggling with Anxiety and TBI: Feeling Alone and Burdened

Have been having really bad anxiety even though I switched meds and have been doing better- having an anxiety disorder and then adding a TBI to it is a lot… fell over (been falling a lot lately :/) ended with me trying to explain to my mom my fear of there being something else wrong and instead of listening she went off and told me another med wasn’t going to fix this (I never brought up meds- I just wanted to express the fear I’ve been carrying about if there is something else going on with my body than what we already know). Made me cry the rest of the night and feel only more closed off to expressing that fear to anyone… I don’t know what to do and now I feel like I lost the person I go to that can hold me in this without making things okay. I feel like I am a constant burden to her so I only internalize and isolate myself more. I feel like I’m being buried alive trying to juggle everything. I’m scared. I’m alone. And I just wanna give up.
