Do tactics and analyse your games! See it like this, you lose because at some point you make mistakes which give your opponent the chance to gain an advantage. As more of these mistakes you spot by analysing your games as less mistakes you do in your future games. Its like the number 1 way to improve in chess. Ah and tactics I suggested because you took a break from chess so maybe you just need to refresh your skills in order to get back to your old rating. Success!
Can't reach old rating

Well,this few weeks most of analysis has done by software,I need to change that.And yes,I love chess tactics more than playing the chess game.
Thanks for reply,somehow I will break the wall

No problem, you will do it if you really want it :). There are more important things in life anyway but we can play some games if you like. Maybe I can help you somehow.
My old rating was 1600-1700 in online chess,but I didn't play a while and now I'm stuck at 1350 with bunch of blunders.I'm trying few weeks to play better,but without success.
