Recurring depression. What should i do?

I have suffered from severe depression and OCD since age 12. I improved significantly for a year, but depression returned at 16. My symptoms include extreme sadness, restlessness, lack of motivation and loss of interest. I once made serious plans to end my life.                                                                                                               For past 3 months, I took Fluoxetine 40mg and Risperidone 0.5mg, which helped considerably. However, 10 days ago, I increased the doses myself to 60mg and 1mg due to insufficient improvement. For the last 2 days, I have felt extremely restless and depressed again. I cannot afford psychiatric treatment, and my family provides no support, so I have been self-medicating using online information. I also have too much free time, no routine, and cannot enjoy anything. My family business will start in 5-6 months. Could the dose increase be causing this worsening? Why does my depression keep returning, and what should I do?
