Feeling aweful! ugh!

Been a long time migraine sufferer but have been on meds that worked wonderfully for them.... unfortunately being pregnant now means weaning off my meds. Things are not going so well. 🤢 I can barely function. I've had to take time off work, I have a constant headache, still dealing with constant nausea & I'm Sooo dizzy. I feel like I'm falling apart. This same thing happened with my first pregnancy but at that time I wasn't employed. I'm so worried I'll mess up my job. I'm praying this all passes soon, though it's not looking good. 1st OB appointment on the 3rd. praying for some help. 😫
