Most countries operate a free national gambling helpline offering confidential support, usually around the clock, alongside online chat and text services. They are used for trading-related harm as well as for betting, and you do not need a diagnosis or a minimum level of loss to contact one; search for the national helpline in your own country.
Peer support is widely available. Gamblers Anonymous runs free meetings in many countries, in person and online, and Gam-Anon offers parallel support for family members. Many national health services list treatment programmes, and therapists with experience in gambling harm work with compulsive trading directly.
Practical steps help alongside support. Self-exclusion or account closure with brokers, blocking software, handing account control to someone else temporarily, and speaking to a regulated debt adviser rather than trying to trade out of the hole. Telling one person is consistently the hardest step and the one that changes the most. See self-exclusion.
