From my own experiences, I don't think that seeing a mental health professional is seen as 'fashionable', certainly not in my circles. During my pregnancy and after Baby was born, I was seeing a mental health nurse and psychologist because I was at risk of developing post-natal depression. I was also on anti-depressants, and while no one came out and explicitly said that what I was doing was a 'bad' thing, no one came out and explicitly said it was a 'good' thing either (except a couple of people). When I spoke about it with particular members of my family, it was clear they were uncomfortable with the idea.
I, on the other hand, think it's very helpful to have an objective and supportive third party in your corner. Especially if you feel that there are things you need help with. There is no shame in seeking help. In fact, I think it takes a lot of courage. And, while I do not advocate a 'drugs only' approach, taking medication can also help enormously.
You must do what is right for you. Remember: those who mind, don't matter, and those who matter, don't mind.
I think that's sad you didn't have more supportive friends - most people I know would think it was great that you were getting the help you (might) need before things got out of hand.
In my opinion, if you nip all these things in the bud, it's much easier to handle than if you let it spiral out of control and then other issues arise (in relationships around you or your feelings or the depth of it, it's much more work to get back on track)
