Transitioning within S&T - Advice needed

Will keep it brief :
- 2:1 from Manchester in Economics
- Spring week at MS in S&T which I failed to convert
- Took a job as a power trader out of university (realise in retrospect this was a mistake) as desperately wanted to get into a trading seat and had never been offered such a high salary
- left after 7 months because shift work was destroying my social life, couldn't find a single place to live in the city where the job was and the company were a start up and didn't have their compensation and benefits for the shift traders sorted out (2/3s of the junior traders left in the same month I did)
- took some time away to get my head straight as had been suffering badly from depression.

Now applying to jobs across trading (and some sales roles) in anything interesting - rates, currencies, commods, and derivs and structured products involving any and all of the above

The issue is I have some relevant experience but it's generally not what recruiters etc. are looking for, so I'm in effect as inexperienced as a graduate without internship experience but a year or so older then that class. Additionally I have a strong interest in this stuff (have a portfolio of trades in rates, currencies and commodes which has gone rather well)

Ive applied to a hundred odd jobs in the last three or so months and have had a few ACs and interviews for all sort of positions but have not had any offers and worse still zero useful feedback from recruiters etc.

On top of that I'm in debt, living at my parents (which I don't like being a burden for), friends are all moving away and harder to see - I feel the whole situation is a result of being unemployed for 6 odd months.

It feels I've hit a wall and I feel increasingly hopeless about getting a job in something that I find interesting.

Does anyone have any experience with this kind of situation or anything which might help in examining what I need to change or things I haven't considered?
