Time to put my delta back on

Recently i have been running a very risky portfolio that much is clear, i have upped my positions from 40% of my portfolio to 77%  yeah i nearly doubled it but it was all to practice making calls and about 20% of that is locked away in long term positions but perhaps the most risky thing is not having any delta, i sold my delta when the profits were up and never got round to buying new delta and as a consequence i have paid the price losing about 3.2% of my profits in 2 weeks. I have learnt a very valuable lesson then and that is "always have a delta" the problem i have is now to get my delta up to what i would consider a reasonable size i would loose nearly all of my cash, or i could sell my long term position at a loss... its a tough call but i think i have the answer....
