Dear Joe L~
It's been a couple of years, so I'll join romantic_thi3f in welcoming you back.
Actually romantic_thi3f has given you some good advice in relation to a disability benefit so I won't attempt to add to that .
I wonder if you realise how much pressure you are under at the moment. You are holding down a job, plus studying at uni and have to deal on an everyday basis with type 2 bipolar and anxiety/depression, conditions you mentioned before.
Under those circumstances I'm not surprised you are having panic attacks. Beyond Blue does have some information about them here that might help:
May I ask if you have medical support for your conditions and the panic attacks? I found until I had that I simply could not cope and actually got worse. I'd also no real idea of my stress levels.
Do you think it might be worth talking to your doctor, or psych if you have one, not just about the attacks but also about the amount of stress that would be reasonable? Then altering your life to have only so much and no more?
This could mean increased medical support, it might mean reducing your studies or something else in your life.
Would you like to say a little more about yourself? For instance do you have anyone in your life to give you support, someone you can frankly talk your problems over wiht and feel cared for, plus maybe a little outside perspective? Someone like a family member or a friend?
I hope to hear from you again
