Being overwhelmed

[blado]

I'm playing as Koinon Hellenon and its around 240 b.c on H/M. I have territories from the west near italy, to byzantium. I'm being overwhelmed at the moment. Every single neighbor is at war with me and I can't take them all. Rome, selucids, pontus, surving makedonia settlements, and the getai too. I've lost a western settlement to the romans already, and pontus took one of my last settlements in asia minor. Getai are biesieging one of my northern cities they I took from them, and will probably fall since that outnumber me there. I'm training a full stack but its taking too long and I'm not sure where I should send it. What should I do to save my small little empire?

I might post a screenshot of whats going on in a while.

I'm not interested in cheating
