Mental health problems are as common among students as they are in the general population.
But it's not just students who have a diagnosed mental health condition that can benefit from counselling.
Alan Percy, head of counselling at the University of Oxford, says: "A lot of difficulties are not caused by medical problems, but by normal life problems, such as family or relationship issues, or anxiety about their work.
"While these problems are distressing, through counselling we can help students to understand them, and then suggest strategies for dealing with their feelings."
It's normal to feel down, anxious or stressed from time to time, but if these feelings affect your daily activities, including your studies, or don't go away after a couple of weeks, get help.
Signs of depression and anxiety include:

Telling someone how you feel, whether it's a friend, counsellor or doctor, may bring an immediate sense of relief.
It's a good idea to talk to someone you trust first, such as a friend, member of your family or a tutor.
This is especially important if your studies are being affected. Many mild mental health problems can be resolved this way.
Many colleges and most universities have a free and confidential in-house counselling service you can access, with professionally qualified counsellors and psychotherapists.
You can usually find out what they offer and how to make an appointment in the counselling service section of your university's website. This free service in universities is available to both undergraduates and postgraduates.
Many universities also have a mental health adviser who can help you access the support you need.
As well as counselling or therapy, you may also be entitled to "reasonable adjustments" such as extra time in exams, extensions on coursework, and specialist mental health mentor support.
Many student unions also offer student-led services. Although the students involved aren't qualified counsellors, you may prefer to talk about problems such as stress and depression with another student.
There are also online self-help services you may like to explore, such as NHS Choices' Moodzone and the Students Against Depression website.
For more serious or longer-lasting mental health symptoms, see your doctor as you may need prescribed treatment or referral to a specialist.
If you have or develop a mental health condition that requires treatment, it's important to arrange continuity of care between your college doctor and your family doctor.
A mental health adviser can support this communication. Your condition may worsen if moving between university and home results in a gap in treatment.
Counselling and cognitive behavioural therapy (CBT) offers an opportunity to explore the underlying issues of your unhappiness or any worries you have in a safe environment, including helping you develop ways of coping.
As well as university or college counselling services, you might be able to refer yourself for NHS counselling. Search for psychological therapy services to find out what's available in your area.
The University Mental Health Advisers Network (UMHAN) represents the network of mental health advisers working in higher education dedicated to providing practical support to students experiencing mental health difficulties.
If you're feeling low or stressed, you may be tempted to drink more alcohol or relax by smoking cannabis.
Consider how this may make you feel in the longer term though, as your mood could slip, making you feel a lot worse.
There's also growing evidence that long-term cannabis use can double your risk of developing a serious mental illness, such as schizophrenia .
Ecstasy and amphetamines can also bring on schizophrenia, and amphetamines can induce other forms of psychosis.
Any underlying mental disorder could be worsened by drug and alcohol use.
