“Bisexual Because Of Meth,” the second episode of Lady Dynamite, poses some worst-case scenarios, then shows that even the worst case is rarely quite that bad.

But ultimately — and in keeping with Bamford’s comic voice — it’s a hopeful story about learning to trust your gut and sing your heart out.
