necessary.” McAlindin v. County of San Diego, 192 F.3d 1226, 1235 (9th Cir.1999) (internal quotations omitted), amended by 201 F.3d 1211 (9th Cir.), cert. denied, 530 U.S. 1243, 120 S.Ct. 2689, 147 L.Ed.2d 961 (2000). She testified during her deposition that she had “feelings of great sadness and isolating [her]self and not talking to anybody or calling anybody.” (Appellant’s App. at 213.) However, she also testified that she was still able to perform her job duties, which required her to supervise other employees. When asked if she' had a support network, Heisler testified that she “caJl[s] a couple of good friends or [her] brother or even [her] friend’s mom.” (Id.) Further, Heisler’s psychologist, in informing Met Council why it was necessary for Heisler to work during the day shift, stated that Heisler is isolated because she worked the night shift, not because of her depression. She also stated that Heisler’s “known support system works during the day and is difficult to connect with when they are working at opposite shifts.” (Id. at 201.) Thus, Heisler was isolated because her support network worked during a different shift than she did, not because of her depression, Heisler has failed to meet her burden of establishing that her depression significantly restricted her ability to interact with others as compared to the general population. See Doyal v. Okla. Heart, Inc., 213 F.3d 492, 496 (10th Cir.2000) (holding that assertions that plaintiff stopped visiting with friends was insufficient to meet burden in summary judgment, where employer introduced un-controverted evidence that employee interacted normally at work).
Heisler next claims that her depression substantially limited her ability to concentrate. Again, Heisler has failed to produce evidence that her depression significantly restricts her ability to concentrate (or learn or work) as compared to' the general population. Heisler testified at her deposition that her depression affected her ability to concentrate, causing her to take twice as much time to perform a task or making it difficult to make a decision. (Appellant’s App. at 215.) She testified during the Veterans Preference hearing that the depression caused a “lack of concentration,” (id. at 353), but did not elaborate on how her depression affected the “condition, manner or duration” of her ability to concentrate. Further, she testified that she could perform her job, including ensuring that money and data were collected, coordinating maintenance staff to fix things, and ensuring that the employees she supervised complied with policies and procedures (id. at 353-54), which no doubt required concentration, and she received only favorable performance reviews. Heisler must do more than assert that her depression makes it difficult to concentrate to survive summary judgment. Her conclusory statements that she has difficulty concentrating, coupled with her own testimony that she could perform her job, does not suffice to establish that her major depressive disorder significantly restricted her ability to concentrate-either in and of itself or as a subset of learning or working-as compared to the general population.
Lastly, Heisler argues that her major depressive disorder substantially limits her ability to take care of herself. Heisler testified during the Veterans Preference hearing that “[w]ith depression it’s just hard to perform manual tasks, everyday tasks like taking the garbage out and sweeping the floor, daily hygiene” (id. at 353), and during her deposition that “it is hard to get out of bed” (id. at 213). However, Heisler also testified that she has suffered from depression for twenty years, yet has lived on her own and maintained employment during that time. She has
