Birth control “crash”?

I’m currently getting off of hormonal birth control and I feel like I’m d y i n g.

Around 6-9pm (which is around when id take my pill) I’m getting extremely tired, lightheaded, weak, dizzy, and horrible restless legs.

I even went to the ER because I thought something was terribly wrong (like blood clot, heart attack or stroke) because I’m a major hypochondriac

And they said I’m completely healthy. 100% healthy other than the fact I have a small UTI.

Did anybody else feel this way coming off birth control or am I just losing my mind?
