It sounds like a good idea to me. Also, what harm can it do to go to a couple of sessions??
It's gets you talking to new people, makes you put yourself out there socially, and emotionally. It can be good for you to get something off your chest in front of a lot of people who won't judge, and also, it will make you feel better about yourself as you're listening to other people and not judging them, you're helping them just by being there, and that gives you more of a purpose and reason to be there than simply "I'm depressed and I'm getting help".
Maybe I need to explain better what I mean. If you just go to one-to-one counselling you're going to "get better" and there is just you and them and your problems, if you go to a group sessions you're not just going there to "get better" but you're also going to see the new friends you make, and to help them "get better".
