I work a full-time, demanding job in the UK, and it's really beginning to get to me. We work to strict deadlines and people heap a lot of stuff on me without due consideration to the rest of my workload.

Keeping myself from getting what I call 'ill' (i.e. rage fits, palpitations, suicidal ideation, dissociation, etc) is an incredibly emotionally expensive thing to do every single day. We have a HR department who know about my BPD and that my family recently cut me off because I spoke out some childhood abuse that I suffered from my dad, and my mum sided with him.

So what I'm getting at is, is there a way to make things easier at work? This industry will forever be hectic and deadline-heavy, but are there things I can ask HR to do to smooth things over for me? My biggest problems are getting in late because of mini breakdowns in the mornings, and getting very anxious and (inwardly) upset when bosses are rude to me. 

Ideally I'd quite and get a part-time job and pursue my hobbies on my days off, but I live in a big, expensive city, and as of recently I have no support, nor do I have any savings. 

Anything you guys can suggest is greatly appreciated. Salutes to anyone going through similar - it's so tough
