This is very sad that Bitcoin and other Crypto currencies are dropping but Bitcoin will raise again. There is always ups and down in everything. Bitcoin will be reached at $100,000 in upcoming few years.
Don't make you upset bro. This is part of trading. There will be ups and downs. It is called correction in trading. Because it went to 20K very fast, it is now in correction phase. And also christmas time effecting the market. In a week or two everything wil be fine.
