My friend told me to see a therapist?

So, I'm gonna keep this as short as possible. But due to the fact that I have not declared a major and taken courses specific to my major, I am set to graduate late. However, my friend was pushing me to take a TON of credit hours so I could graduate early. I ended up telling her that I didn't think it mattered how long it took me to get done with school because I don't foresee myself being happy in the future and I don't think anything I do is going to matter anyway. Then she kind of shut down that conversation and highly suggested I talk to my parents about seeing my therapist again because she's worried. I will admit, I attempted suicide a year ago, and have seen a therapist in the past. I do feel kind of bad again, but why does she feel the need to tell me that..?
