Depression

Hey all! So I've been going back and fourth about going to my Doctor and asking to be put on an antidepressant for some time now. I know I need it as my whole family suffers from anxiety/depression badly. I've been gaining weight uncontrollably, not going out like I used to, some days I'm so anxious I can't even get out of bed. I know it's totally normal and I shouldn't have this thought, but I haven't went because honestly I'm kind of embarrassed. I feel weak asking for drugs to help me feel like a normal person. Any tips on how to get passed this complex and just go? And how to have this convo with my dr?
