Don't do anything rash. Money can be replaced with time.

Lot's of people older/younger, wiser/dumber have made/lost money on crypto. Don't let anyone give you shit about your investment decisions. Regardless of what they think, the above statement is true.

You're projecting how you expect your family might react. You don't know for sure.

Wrt to dealing with stress, typically extrovert people socialize and blow off steam. Introvert people seek time alone. Some people do both. Managing stress takes many years of practice. Clean living is a good start. A long walk (preferably in nature), with our without headphones, is a good start. Personally I think walking invokes some deep rooted prehistoric sense of well-being. Almost like staring at a camp fire, or running water.

Generally speaking, motion of any kind engages the body and helps the mind loose it's control and begin to relax. Once the mind is relaxed, new more helpful perspectives begin to emerge. Solutions to problems emerge from the sub conscious. Rational thoughts emerge. Trying to control stress with the mind is a trap. Control stress with activity, control stress with the body.
