Exactly how many months you didn't stake? If you have a lot of tiny UTXOs (coins from faucets for examples) you may try to combine all into one or two. There are threads on reddit. Also I assume you have newest version of the client and unlocked for staking. As I said, with ~6k coins 3 months without a stake can be nothing extraordinary. This probabilistic nature...
I'm afraid nobody found the way to make it better for the poor. Instead of 100k with many UTXOs person could have 20 separate addresses with 5k each. And still he would get same share of staked blocks. Nothing changes. The only way for small holders is pool.
Had to say, by somekind of miracle...I just staked for first time :D
