tl;dr - needing advice for intense and sometimes crippling anxieties

hi, i’m a 23 yr old female, and i’ve never been fully diagnosed, but i have been diagnosed with depression and anxiety, with an added note as of three years ago that i could possibly be borderline.

i’ve ALWAYS been depressed and anxious. i went to an inpatient facility at 13, followed by two years of mandatory counseling. due to bad experiences with the counseling, ive been extremely hesitant to go back into therapy and get a full and proper diagnosis. 

and that’s worked okay for me so far.  

lately though, i have a whole new slew of anxieties that i didn’t have a few months ago, or maybe i did have but not to this extreme. most of them are in regards to food (i have always had a lot of problems with texture) and thinking it’s going to make me sick. another one is when i’m in the car, normally i’d be a little anxious in the passenger seat (assuming that’s a control thing), but now any small jerks or drifts or literally any minute thing that i perceive as “not normal while driving” almost cause me to have an anxiety attack on spot. 

the only major change in my life recently was a move in July, and this started more recently than that. i’m struggling to understand what’s causing   all of this, and struggling even more trying to cope with it. 

i’m really just looking for good coping tips for these anxieties, general advice, or just someone to say they understand. thank you in advance for any help 🖤
