Note your desire to ordain.
Start saving money and doing research, but otherwise continue with your life, bringing awareness to everything you do (very glib statement I know).
Maybe join a dhamma/meditation centre if there is one. Travel, if you can, to different monasteries and spend time in them to get a flavour of monastic life (advice given by Ajahn Amaro to me).
Revisit this desire in a month, and see if it has strengthened. If it has, repeat the above, then revisit the desire a month later. And so on.
My point is that if this desire remains strong, or stronger, in, say, 6 months time (or whenever is appropriate), then you'll know, with a clearer head and plenty of hindsight, whether this is a genuine calling that still resonates with you long after your current situation has passed, or whether it's an immediate 'escape' from your situation (which, mentally at least, you'll take with you wherever you go anyway).
I revisit my desire each month. For various reasons I cannot act on it right now. If, in a year or so, when I revisit the desire, it remains strong and continues to resonate, then I'll not only be in a position to act on it, but will know that it is a strong, wholesome and sincere desire that has persisted throughout everything that has happened (and I have no idea what will happen), during which I have continued my practice, but also my lay life, in a wholehearted and committed manner.
