It's likely you have been scammed and sadly you are not going to get your money back but you can help save someone from being a victim by giving more detailed information  as to what happened, like the name of the platform, how you got to know about them.
 
Are you asking for donations? Are we running charity here? This is not wise at all and I'm beginning to question the authenticity of your story. How are we sure you truly got scammed or you are not the one try to scam others?
