Hey buddy,
Another unfortunate part of living in Ireland is that there are next to no mental health services, and I'm sure cost is also probably an issue for you. I'm fortunate that I'm coming out of about a 9 year stint of on and off depression, and I've been out of Ireland for a few years so I'm not majorly in the loop with what services are available, but Bressie seems to be doing some good stuff with A Lust for Life - I think they have free online CBT courses which I think would be a good step for you to try http://www.alustforlife.com It can take some time to find the right kind of help for you (and the right person to help you), so online might be a good first step - personally, my first counselor was a nun (i was a raging, agnostic teen at the time so that lasted about 30 minutes), and my second attempt was an in-house counselor at my GP in the UK who asked me to fill in a questionnaire before my first visit. One of the questions was about whether or not you had recently thought about suicide, to which I answered positively. However, I was told that my quiz scores were too low and that I didn't actually have even a low form of depression. Complete confidence killer after building up the courage to go and speak to my GP in the first place after years of inner turmoil - the fact that the previous week I wanted to walk into the canal beside my house and just let myself sink down and drown obviously wasn't depression! It takes time to find what and who works for you - I've personally gotten a lot out of just speaking to friends about when I've had low points. You may be surprised how many of your friends feel similar.
I wouldn't be so tough on yourself re: relationships. I'm 24 and I've still not had a boyfriend - I think, like me, you probably need to work on loving yourself first before hitting relationship town. It's really not the be all and end all that you're not with somebody. "If you can't love yourself, how in the HELL you gonna love somebody else?". Also, look at all the thirsties on here looking to put out simply because you've mentioned you're a surfer ;) You won't have any issues finding a guy! Give it time
Sounds like you're a bit conflicted about surfing, too - you seem to be solely blaming Ireland for lack of opportunity (which is not untrue), but this isn't a rut that you can't get out of. If surfing is what you want to do as a career, make it happen - if you know it won't happen in Ireland, look into going abroad. Yeah, it's scary as hell but it might be the only way to kick-start your professional career. If that's too much of a commitment for you, you might want to weigh up if you want surfing as a career, or just a hobby? Maybe it doesn't have to be either - maybe you can find a happy medium and slog it out in Ireland. I'd maybe try connecting with David O' Caoimh - he's a professional Irish wakeboarder and could probably give you some advice and reasonable expectations for trying to hammer down sponsors.
TL;DR - Build up your mental defences. Work on loving yourself. And drop that damn Catholic Guilt that we all carry.
Stop living to society's expectations of relationships and beating yourself up over it.
Have a good, long think about what makes you happy and which direction you want to head in. Network with others who've made those journeys. Make your journey happen.
Final tip - find your tribe. I've surrounded myself with negative people for so long. Find a solid group of people who love, encourage and inspire you. The kind of people whose faces light up when you tell them about your next adventure. The people who put a spark in you, rather than dragging you down.
I hope your road to recovery goes well, it's a long slog but you have a place in this world :)
