Whispering little words of deleterious actions.
Telling me how worthless I am.
How I need to stay inside; the outside world is dangerous.
How everyone will leave me.
I've become so overwhelmed with my school work, though it is only two courses. A lecture and a lab. Fairly easy, just tedious to study for.
They are classes for a degree I do not want, yet I continue studying for it with such vigor that I wonder if I subconsciously want to become this...I'm diverging.
I have very little, if any, social life. I have a decent grasp on my anxiety the majority of the time. But this upcoming month is filled with things to do...and I am not an outgoing person. My birthday is less than two weeks away (the magical drinking age of 21), the upcoming weekend I go on vacation, and March itself is full of fun things. No, that's not sarcasm.
So...why am I so scared? These are all good things. They are healthy things; things any "normal" person would love to do.
But I cannot shake the sense of it being overwhelming. It is an all encompassing feeling. It causes dread in my stomach, and I've found that going to class if becoming harder and harder (at least attendance doesn't count). I tend to curl up in my room, sometimes sobbing, resisting urges to relapse into harming...and I can see that I'm starting to become agoraphobic (having studied and gotten a degree in psychology makes one super aware :/). I've tried distraction methods, upping my medication dosage (which helps when I lapse into panic attacks and when this feeling invades my sleep schedule), and calming methods. Calming methods help take the edge off the most, but: it's still there

I'm still trying to claw myself out of a hole from a heavy depression bout, I'm not there, and every day I waver on my progress of getting out.
I am so sick of hearing, "It's all in your head."
I barely leave my neighborhood, unless I absolutely have to. The idea of going anywhere is exhausting, let alone doing it. And I'm afraid, constantly. I don't know why, but it's a subtle feeling that I'm going to be alone (thank yooouuu BPD

I don't know how to tackle this, and it gets worse at night. I drop into an abyss at night; everything becomes 10x worse than in the day.
I see my long-term therapist this upcoming Monday, but for right now, I have no idea how to deal with this, even after dealing with anxiety and depression for so long...
I need advice, because I'm at such a loss on what to do.
