Feeling hopeless: rant

My birth control I feel is failing and I have an appointment this week with my ob. After thinking I found a pill that works I’m back to where I started a year ago. Just feeling hopeless and anxious thinking about going through the process of finding a pill that does what I need and doesn’t make me feel like death. Thinking about going through blood testing to check if I’m anemic, have endo, or have thyroid issues all over again is exhausting, I just wish I could find something that works.
