Yeah, I would probably deposit more. Or, if I was feeling like it was all futile anyway, I'd play a few $1 sngs or go to the micro ring tables. Probably blow the rest there... or start building it back up. Personally, I don't like playing with such a small BR, but there is a particular joy in turning it around. The zero to hero concept is very intriguing. I know any number of people who never deposit and who are capable of building a bankroll from scratch. And have the patience to do so. Are you one of them?
The alternative to depositing is to build up your BR in freerolls and very inexpensive tourneys. There is a 10 cent one every eve from the FT forum -- the pw is easy enough to find. There are cheap sats to the Daily Dollar on FT. Look around and see what you can find.
There are several forums (besides this one) that hold freerolls for active members. If you look under the private tourney tab, you can find the names, then go look for them. Join a few and do what you need to to be eligible. Freerolls are kinda wild, so your skills and luck both have to be on.
Next time, if you want to see how the pros keep their money, try using bankroll management. (See Chris Ferguson's rules on bankroll managment.) You do have to be a decent player for this to make any sort of sense -- a losing player can only extend the times between deposits. If you are not a winner, you need a budget.
If it is just a fun hobby for you, then just try to keep your deposits at a level that is equivalent to what you would normally spend on entertainment. If you are regularly finding your poker money running out, you need a budget. Figure out what you can afford to lose. Be realistic. When I was just playing for fun and learning (i.e. mostly losing but enjoying it), I would deposit no more than $50 a month. If I ran out before the end of the month, then that was it until the next month. That was my poker budget -- which is different from a bankroll. Your budget may be greater than that or less.
I now have a bankroll, and not a budget. While nowhere near excellent, "bankroll management" is now something I can use. Somewhere along the way, I improved a bit, and have not deposited for over a year. I do not anticipate soon getting to the level where poker will be providing a regular income stream (wouldn't that be nice?)-- I am just grateful that it is no longer an income drain.
It's very important to be realistic about how you are doing.
