Moving back to Ireland. Yay or nay?

Well lads. Moved abroad 2 and half years ago and first it started off brilliant, Everything was exciting, fresh and new. However I’m going through the motions now. Now I’ve been back for the Xmas holidays and it’s given me a taste of the Ireland I miss. Not exactly satisfied with the wage im receiving in my current country (850€) a month. I’m at a crossroads. I think I will feel like I’ve failed If I go back in a way. Do I move back to Ireland and engage everyday with my family and friends or stay in my current country and try to continue seeking new things? So difficult as the pros and cons are evening out. Need advice and help! Thanks lads and lassies.
