I don't really have the money for therapy, nor am I sure how helpful they'd be :/ i've seen therapists while I was at school (it was free because it was part of our tuition) but I personally didn't think they were very helpful. I'm not sure if therapists are the same throughout different institutions though.

For the career anxiety, most of the advice I received was to follow my passions or interests (which I don't have, or am unaware of). For the being reserved part, they put me through a set of workshops focused on overcoming anxiety, but I had no problem with that because it was all very shallow and constructed. I hadn't mentioned anything about the worthlessness because it wasn't my priority at the time.

A few other things I didn't find helpful: they tried to get me to do some mindfulness exercises, but when I tried those, I either became bored easily or I literally had no thoughts whatsoever to take note of. And, whenever we talked, I detested when they said things like, "I'm sorry that happened to you", or "You were very brave for doing x". For me, it doesn't matter if you feel sorry for me, or if you think I was brave (or whatever else) for doing something. The events were too insignificant to be of value to me. I do see a lot of people using those phrases, though, so maybe those sentiments are helpful to some people? I dunno, but it's curious to hear many people use it :/

tl;dr Not sure if therapy is something that will be helpful for me + don't have the money for it
