Is it normal to get "blocked" intellectually?
I was so creative when I was little. I loved to draw, and I think that I was quite good at it. I also used to write lots of short stories, plays, poems and even songs. I used to read a lot as well, mostly novels, but also lots of articles about history and science. I had a lot of talent for learning new languages and I was very ambitious about it (I wanted to learn at least 10 languages). I was always praised by everyone about how creative and intelligent I was, which made my truly happy.
I don't know when it happened exactly, but I started to feel numbed intellectually. I haven't been drawing for years now, but I really don't feel inspired at all. I don't write that much anymore either and now I usually make many mistakes now. Whenever I check something new that I make, I instantly feel like it is crap.
Also, I don't read that much anymore and I grew to hate long novels for some reason. I am studying German now, but it has been months and I feel like I am not assimilating anything at all, while my classmates do great. I can't even hold intellectual conversations for long... I have felt like the dumbest person in the room many times already.
I am 25 and I don't do drugs or even drink alcohol. I had depression for a long time... but I don't think that could be the reason. If anything, I actually felt smarter when I was depressed.
I have been unemployed for a while now... and I even feel scared to get a new job, because I am afraid to "screw it up". I don't know, I just feel dumb.
So, is this normal?
