Hi Sparky, do you think the stress, anxiety and sheer effort it's taking you to "get from A to B", do "x,y,and z" is just consuming you so much that you're almost on autopilot in relation to the more "mundane" aspects. Just so much going on for you it's difficult to process the extra's??
Then again when we've so much to cope with certain areas of our "minds" can shut down/take a back seat. We can only cope with so much, right?
Lack of sleep can absolutely have a big effect as well, whereas maybe your natural response could be to just relax/rest because you're "physically" tired, your anxiety could be working against that making it even harder to function.
I should ask if you're taking any meds as well really, if you are maybe they need adjusting???
As for working through it are you seeing a professional about the anxiety (and do you think possible depression???)? Maybe it would help having some/some more input.
Aside from that though can you really pin down any triggers or thought processes leading up to those feelings. Perhaps working with those could help.
Or maybe a bit of desensitisation. Start from the beginning, set yourself some small goals and gradually push your levels of tolerance.
Any distractions you could use to help you when out as well?? e.g. wearing headphones/listening to music or calming sounds.
Perhaps you could try some meditation or mindfulness techniques as well?? Whether you're using them when out or planning breaks when you're out when things are really tough to just sit and spend a few minutes on them. Worth at least a try?
Noted you mentioned lectures as well. Do you think that college (??) work is stressing you a little? Perhaps if you talked to lecturers (??) for a little extra support and tried a few different study techniques that might help just a little?
Just a few thoughts, sorry if you've heard them all before. But above all for now: Get some sleep!!

Around if you want to talk some more though.............
