I think I am suffering from depression

Patient: Married with two kids. I work full time. Always on my feet. I believe my husband is cheating on me. I have now stopped eating. Going on my third day. Everything either makes me mad or cry, I have no patience and I lost interest in doing anything. Or going anywhere. I get very nauseous several times and day and light headed. Should I try to get on antidepressants and how unhealthy are those for you? I’ve heard they have so many horrid side effects. I have no one to talk to about this. Feel so alone. I have to watch tv til 2 in the morning every night just so I can fall asleep. I just want to get better so I can be the best I can be for my kids
