Hi kaliedo, I was diagnosed with GAD in my last year of uni after bout a month of tests. It was really hard to go in and i missed about a months worth of lecturs jus becoz evrytime i went i had an anxiety attack. The more i avoided uni the worse my anxiety got and the more i felt overwhlemed. My one piece of advice is keep your tutor informed of what happning and if possible get your doctor to contact your tutor. This really helped me.
Second thing its gets better, after two weeks on meds I was to something like myself.
If i was you i would give myself 3 or 4 days of no stress just chilling out. Then start trying to catch up. Remember to do things in little baby steps.. set yourself a realisic target for each day then go do it. You get a nice sense of accomplishment if u manage to complete your target it will help combat the depressed feeling.
Also i found going to the gym reallly helped my mood, it may help u too.
You wil learn to get some control over GAD eventually.
I hope it all goes well for you. Please keep us informed of how things go, and you'l prob find the depression clears quickly once you get back on your feet :P
All the best
P.S welcome to HW
