Struggling with Mental Health and Medications

Hey all, I'm new here, it's nice to meet you all 👋 I guess I'm putting out a flag to see if anyone else experiences life similarly. So, I live in Australia and I got's the ADHD (I actually think I'm Autistic as well, definitely not gone down the diagnostic route tho, not overly bothered), OCD, MDD, GAD and I've not been doing too well over the last year or so (who hasn't, right? lol) I got an adhd diagnosis when I was 5 and tried Methylphenidate and Dexamfetamine, apparently I used to spit out the pills, but got re-diagnosed around 12 months ago and have had two trials of Dexamfetamine and lis-dexamfetamine. I found it difficult to manage diet and food frequency on stimulants - I get nauseas if I don't eat on time (e.g. 3 hours) but appreciated the cognitive improvement/ working memory improvements, "staying on course" etc but I found it made emotional availability (e.g. spending time/ talking etc with my partner very difficult if it wasn't "on schedule"/ before the medication met it's half life. My biggest struggles are holding down a job and being a "normal person" and managing my anxiety (e.g. food shopping is excruciating) - I haven't been able to work in 12 months. The anxiety of being that square peg trying to fit in a round hole (trying to be "normal") was too much for me, where the depression kicks in bad (you know what I mean). I guess I'm at a point now, where I can't manage the anxiety despite medications as and therapy unless I take stimulants. But the stimulants are just difficult for me to manage. Went to the grocery store yesterday and I can still hear the sound the trolley/ cart made, it was an overload and chaos. I usually shop online and pick it up, so I don't have to enter the store for too long (and for the bargains lol). I'm just laying here thinking "how the hell will I ever go back to work?" - it's like I've quite literally hit my personal thresholds for being able to manage my life. I did well for 4 years prior to leave from work, but I notice my life was quite "sterile" back then, it was simple and all I cared about was work - it was everything to me, the curiosity and excitement it brought me. Now, I'm just a ball of anger, distress and disorganisation. I recently got that desperate for help that I started to see a GP about vitamin and minerals, so had tests done and added them into my medication regime (previously just a multivitamin, D etc). The latest medication I started (and continued) is Mitrazipine, which seems to dull some anxiety during the day but I struggle to awake before lunchtime. Just struggling to see what to do with my head and the way I perceive everyday things and how I react/ behave. I'm 33 and extremely lost. In summary, I guess I feel completely alone (even though I now live with a very supportive partner) and feel worthless as I am not working because I'm struggling in my head. Anyone else out there on similar medications, perceptions and issues?
