Irregular periods and symptoms

I'm on day 90 of my cycle and I'm going crazy with over analyzing my symptoms. More than usual cm, constantly hungry, but full as soon as I take a bite and food is just blah. I have trouble falling asleep. And I've been so emotional for two days. I keep getting bfn. I got a bfn yesterday and just bawled my eyes out cuz now I'm thinking something else must be wrong with me. I got tired of tracking my bbt because ovulation just isn't happening. I guess I'm just wondering how ya'll deal with getting negatives and not losing hope. I'm planning on getting a makeover tonight, and planning a date night to a comedy club with my hubby tomorrow. What are your ways of getting over bfns?
