<human>: Can you summarize the given text in a few sentences?

I'm hoping to hear from or talk to someone familiar with the Americans with Disabilities Act, I live and worked in Pennsylvania. I'm diagnosed bipolar 1. I worked for a marketing agency as a web developer, my work was always praised and always done early. After about 9 months of employment and a strong depressive episode I began to be late somewhat often, like 5-10 minutes. I was given a few "talks" and finally decided to write a letter to the CEO disclosing the disorder and how much it affects my time management as a general symptom and even more so during manic/depressive episodes. I met with the CEO and he wasn't willing to accept my reasonable accommodation idea of staying late for the amount of time I was tardy each day, but raised my salary a few dollars each month to cover health insurance, since I was unmedicated at the time (I'm also a single mom and only made enough there for rent/daycare/necessities) -- this was also around the time of my yearly review where raises are given anyway and I was told that that was considered mine. I still stayed late every time I was tardy anyway up until I was fired. I got a psychiatrist appointment in January, was prescribed lamictal. I let them know, from experience, meds don't just start instantly working, and are often not even the right med the first time, there's a lot of trial and error. Well, I wasn't magically cured in 2 months and they fired me Friday for "excessive tardiness". They actually avoided telling me the reason I was being terminated until I found their company policy outline where they claim to always confirm reasons for termination and emailed them requesting an explanation.

I'm wondering if this is worth consulting a lawyer about, the company has about 30 employees and no HR department. Being late never affected mine or anyone else's job, I literally just went in and sat at a computer alone all day for the most part.
<bot>: Am bipolar, disclosed illness, fired for being late even after explaining how disorder affects time management, and requesting reasonable accommodation of staying late to make up for missed time in morning. Is it worth consulting a lawyer?
