I’ve had so little practice in actually using languages

This may be true, but you have surely gained lots of knowledge and skills in the language classrooms of your past. They will be a good basis when you find yourself in real communicative situations.<br><br>

Find yourself someone to talk to. Suggest to your best friend that you use another language together. Look for opportunities to talk to tourists and foreign visitors. Mental exercises, that is, using your inner voice and talking to yourself can be fun and beneficial to your speaking confidence: for example, give imaginative speeches and talk to yourself in the foreign language on the bus, metro or train. Be patient and encourage yourself!
