Hi Santoro,
I can tell you from experience that is difficult but not impossible to get out of that particular pigeon hole you are in. It also going to take time and probably a few backward steps on the career ladder. Obviously if you can afford to go back and re-train then that is probably the best route. However,you need to know what it is that you want to do before you can attempt this. Another possible compromise would be to stay within the industry but seek out different roles. You should probably be able to get other roles in TA, custody, shareholder services etc. Although chances are they are not much more stimulating than FA. Compliance is another option which might be a little more interesting. A course in anti-money laundering legislation and compliances practices would help. There might also be opportunities to research funds generally for websites like trustnet.co.uk or morningstar (i can't remember the dublin-based firms but there are a couple iirc). You could definitely move into all of these areas with a little effot while at the same time staying employed. Also check out the National College of Ireland to see if there are any part time courses you could take.
These are suggestions to help you gradually move away from what you doing. However, ultimately you may have to revisit the drawing board. It is going to take, effort and determination and a willingness to take entry-level positions (not to mention luck) but you will get there in the end if you are prepared to keep trying. And your current experience will always stand to you.
best of luck
