What do I do when my family doesn’t believe I am depressed due to a lot of people saying they are depressed too, I have no support and don’t have as many friends?

That's a tough situation you're in. I used to be in your position as well, I know how you're feeling. Talking to someone about the problems you're facing is a really important step to take though. So what can you do if you should have no one? You can either seek professional help (a psychologist nearest to your place) or reach out to a listener here on 7 Cups! We're not called listeners for no reason!

If they don't believe you,then you should try seeking a professional help from someone that could help you out

Sometimes it can be useful to provide your family or friends with objective resources (such as mental health information sheets from your doctor or from online resources), This way it's not a matter of your opinion versus their opinion, but that you are displaying symptoms from a verified checklist, in much the same way as a physical illness might be confirmed. Sometimes the biggest impediment to understanding mental illness for people is its invisible nature and the fact that they aren't experiencing the things that you are experiencing. If you can refer to something objective like that, it might help to shine light on the subject in an understandable way. All the best.
