I didn't really want to "jump" into this thread because it really seems over saturated but I think I have a new perspective to add...
OP, I've been where you are now (for the last two-ish years) and when you're like this,
you can't make the best decisions about your well being. I know this may make you angry to read, but it really is what you need to hear. And
just because this isn't what you want to be told, it doesn't mean that you should ignore it...
...You said that you find your dad in hysterics frightening, do you honestly think that it'd be better for you in a psychiatric hospital?
... I think you're looking (like I sort of still am) for this person to just come along and make life durable again but that person simply doesn't exist
...I've got some tips from my experiences:
-try exercising such as taking an hour's walk in your local park. Feed the ducks, even? I'm sure that'd be tons better for your mental health than being cooped up in A&E for hours on end.
-try mindfulness meditation for
20 minutes every day. I know you mentioned that you tried it before, but if you're this desperate for help, then it's worth a shot as you're already spending vasts amounts of time in A&E.
- eat healthily
- leave the house everyday, perhaps take a walk around your 'block'
- try volunteering, it'll make you feel good about yourself
- try to get enough sleep (keep away from the TV, computer, your phone; have a bedtime routine; have a shower; take a nice walk beforehand; have a glass of warm milk; make sure your room's completely dark; read something nice beforehand-like Harry Porter?!)
- keep off the internet and social networks- it/they can be soul-sucking :L
- have you asked your GP about local groups like ones for people living with depression and anxiety?
- join an art class, join a drama group, join a local amateur sport club
- just generally be kind to yourself
- take advantage of the Samaritans 24/7 phone line on 08457 90 90 90
All the best for the future,
