I feel so fucking shitty on birth control .

Alexandra
I started taking the pill about a month ago. My doctor told me it takes a few months for side effects to go away / to let your body adjust.
But I have terrible terrible nausea , I can't keep food down or even smell it . I have consistent head aches and mood swings I've literally been crying every day for no absolute reason.
The most troubling thing about this to me is the nausea I'm 2 years recovered from annorexia and I was eating normally and finally happy before I started taking birth control.
I'm also really easily prone to getting depressed and I'm just worried about my mental health right now I didn't think it would affect me this badly . 
I want to get off of it but I'm in a relationship with a lovely person but I'm only 20 and I don't want to risk getting pregnant. 
Obviously condoms are the only other option if I get off birth control .
But idk what to do , I wanted to make this post because I feel like my emotions are all over the place and idk what to do . I'm leaning toward getting off of it but what's anyone's opinion ? I really just need emotional support lmfao . 
I literally feel like confetti bc I'm just so all over the place.
I also don't want to get the shot or any form of IUD . 
My boyfriends been a trooper calmly dealing with my consistent mood swings but he's also wanting me to get off of it bc I feel so unhappy. 
Help a girl out 😭😭😭😭 
Should I waite it out or just stop it all together ?
What have your experiences been ? 
Anyone else get hit w side effects this severely ?
