I need support from people who've been through it and reached the light at the end of the tunnel

Hi everyone, I have taken 3 doses of my Lexapro at 5 milligrams, and I'm having a very hard time... I was debating if I should take it for months, but wasn't sure I really needed it until this last Tuesday, I experienced something that kind of triggered a deeper anxiety and I decided it was time to start.... In his first three days, I feel lve experienced intense increased anxiety, I feel cold and clammy, but also very sweaty and sometimes hot... I keep getting this burning flare of anxiety in my chest, especially at night, and it keeps waking me up every couple hours... I feel hungry, but sometimes it's hard to eat, I get shaky... I don't know how much of what I'm feeling is the Lexapro and how much of it is my life circumstance, but I just need reassurance that it gets better.... I've been reading a lot of forums that say it works, but sometimes these first couple weeks are hell... All of this is normal right, and it will get better?
