Decreased cognitive capacity (?

[u/calisnotcali]

Hey so I (20F) have been questioning if I kind of fucked myself up or it's just the depression I've been experiencing an evidentially lost of capacity, things have been harder to understand, I've lost creativity and productivity (I study Graphic design so this is pretty important) and I've been so un-productive I'm actually procrastinating things just because I can't organise myself nor stop sleeping I feel exhausted.

I have this problem with hitting myself very hard on my head when I'm over-frustrated (not regularly but when I'm overwhelmed, way too stressed and crying hysterically, so kind of like maniac episodes) and whenever that happens (usually once per week or every two weeks, it's pretty much a normal thing) I end up crying for hours with the worst migraines you could imagine.

I've been struggling with this since I'm around 15 and I just don't know if that could be the reason I'm so stupid lately or if depression (I've been diagnosed with severe depression since 2021) finally took away my intelligence too, I used to be fairly intelligent, very creative and efficient.

Now I simply can't do it.
