Day 6-side effects kicking my butt

I’m on day 6 of lexapro 10mg. I’m super fatigued but can’t sleep at night; my anxiety is worse than before I started but feels like it might be slowly calming down; I’m obsessing over EVERYTHING; I’m dizzy and have a constant dull headache. I know these side effects are common and usually disappear within about 2 weeks but it would help to hear it from people with experience with similar side effects. A lot of people that I’ve talked to say once the side effects subside I will be feeling much, much better but I’m struggling right now. I would appreciate any help getting thru this hard part.
