You can absolutely talk to your friends and that might be all you need. People often choose therapy when they find that chatting with friends doesn't deeply change how they're feeling on the inside. If you've been struggling for a while and nothing your friends say really helps, it's time to take your life and your happiness more seriously. Help from a professional goes deep and wide. People find they can be much more brutally honest with someone who isn't part of their daily life and social scene.
