At a distance, like on here, pretty comfortable because all I'm doing is directing them to the best places for advice and i'm not personally involved. In a more personal capacity, like a friend, more uncertian as I have my own limitations and would always want to do more to help and be there for them. It's also a bit heigher stakes in some ways and I'd feel more responsible for anything that happened. Also puts more pressure on my mental state and means I have to balance things.
Tried to help a friend with some issues when I was at the height of my own and it was just impossible to get the balance right, especially since I didn't really know what I was doing. I now feel more confident in the advice I can give, having been through at least some issues myself and being somebody who tends to keep an open mind to most things, but still feel like nobody can ever be fully equipped to deal with something like that.
Would feel out of my league dealing with any complex issues like OCD, bipolar etc and probably wouln't be good with anything that makes them too distanced or grumpy with me cos i'd eventually take it the wrong way, but I like to think I'd be decent with uderstanding and being there for somebody with general depression and anxiety sorta stuff and hopefully capable of giving at least some good advice for stuff I don't understand and making sure they know their options and have some sort of net.
I also have a terrible poker face and will either tear up or awkwardly smile in tough situations so... yeah better with words than actions :P
I think the hardest part for me would be if I ever had to betray somebodys trust and call in help for them. I feel like that's a decision I would end up messing up because i'd be too worried about them not trusting me again.
