I do have my ups and downs and I doubt myself sometimes. Yes, living with depression is difficult and it really helps to speak to someone.
Friends & family can help but its not the best as sometimes they don't understand. Worse still, sometimes they try to help but end up messing things up much more. But its with good intentions though.
I found this therapist who is very kind and patient. She uses many creative techniques to help me. I've been seeing her for many years. Slightly pricy but I think its worth it as she helps me out of my depression. The most important I feel is to find someone genuine, not those only interested in your money.
