Hello,
Remember that everyone reacts differently to medications in this case this antidepressant (SSRIs), so it will vary from person to person besides it takes 6 to 8 weeks for Citalopram to reach its full therapeutic effect, so hang in there, you will get better.
As you mentioned it is important to keep oneself busy, try, if you can, reading, watching films, etc., as you say it is cold outside, but you can also exercise indoors and find other activities to keep your mind busy.
Be patient and never lose your faith that you will get better.
All the best, masso
