I try to be as tolerant and helpful as I can (I also have depression and can relate).
Because I also have depression, I can be very empathetic, but I can only help them up to a point (I have to help myself also). If they become too 'clingy' or too 'needy', the only help I can give them, is referral to a professional who is more helpful than I (I just get overwhelmed too easily).
I have found others have little sympathy towards my depression though. Just yesterday (after coming out of hospital from a stress-related episode), the doctor told me to get full bed-rest for a few days and I was taking his advice...when my family 'phoned me up, wanting me to immediately do this and that for them...
When I told them 'no way'....when I told them I had just come out of hospital, they went; 'there's nothing wrong with you, you are just very lazy' and 'why are you 'sick' all the time? you are just doing it to get attention' and 'snap out of it and do what ever we tell you to'....I heard the words of my doctor ringing in my ears...and I said 'you know what? get effed. Yes, you all heard me, just eff off'. They went 'if you really want this, we'll never speak to you again'. I am like 'good! now just eff off' and I hung up on them.
So, it matters not what other people think about my depression. I have reached the realisation ages ago, that they will never understand it and I am the one who has to live with it, so apart from paid professionals who actually do have my best interests at heart, I am pretty much on my own with it.
