Hey man, I really know the struggle.
I played microstakes mtt's for a few years also losing money.
But now I've been working on my game and I built myself a bankroll that makes me capable of playing low stakes (and even mid stakes through satelites).
I have a few thoughts to share with you.
First of all, I don't know how many tables you play at the same time, but I would like to suggest playing a maximum of 4 tables at once or even less.
That way you'll probably make less mistakes because you have more focus and more decision time.
Also I'd like to tell you you'll probably need to work on your poker fundamentals, since you're cashing a very low amount of games.
Try not to register tournaments that are running out of late registration time too much, since you'll be more likely to end up busting within 5 minutes or less..
Don't try to play hyper-turbo's since you'll have to deal with a sh*tload of variance.
You should also be aiming to play smaller fields since you'll be more likely to cash and make a potential deep run.
Following this, I can suggest you play the $1,50 45man sit n go's. They have a small field, not too many good regs. There is way more variance in playing mtt's than there is in sit n go's.. You can even play 18man or 9man sit n go's if you like (the 9man sit n go's offer a top 3 paid structure, meaning a 33% chance of cashing each time. The payouts aren't going to be big, but you'll very likely increase the number of your cashes and therefor stabilize your bankroll a lot more, resulting in softer downswings.
In your situation, don't focus on big results. It's way more important to make sure you're losing less money to start with, then try to become a break-even player, etc.

Remember, slow progress is better than no progress.

Agree with strewbarry, all I can add is don't bother as much with the 1.10 hot/big/BB tourneys as they get thousands of people and even if your super good its hard to not run into a bad beat somewhere and bust.I would play them staring at the 500$ uptop thinking I have a chance. I have just started buying into the 2.20/3.30 tourneys with a smaller guarantee say 500/750 which only get around 300 people rather then 3000 and cash a shitton more. So its a lot more rewarding.

I had the same struggles when I started playing online at the micro stakes. My best advice to you is don't do anything fancy! You only need to play the game straight up and bluff as little as possible. I agree with the other 2 posters, smaller fields and lower GTD's yield less luck factor and allows more skill-based games. Big key is to adjust to the players' game on your table and watch for tendencies. 10% of the field are bluffy, 10% of the other players are stupid bluffy, the other 60% is a bunch of passive or very loose players, and the final 10-20% are players like you trying to score and really grind. If you're trying to be complex as if playing high stakes or like the pros you see on TV ... don't! You really don't need to worry about any complex strategies as this stage at all and that's where a lot of micro stakes players get it wrong and lose a lot of the time. The same goes for micro stakes cash games. Stick to tried and true straight up poker tight aggressive and you'll see a vast improvement in your game and see more cashes and final tables. AKA K.I.S.S. method at the micro stakes for the win!
