From personal experience; I recommend it. Whether through OC or canon characters RP can both be fun and a way of improving your writing skills; and even developing OC characters if you wish! I've been through an RP burnout myself; need to find a way to get back in. XD
I highly agree. The last time I had an RP the other person stopped responding. It was on the amino app so I shouldn't have been surprised. It kinda hurt to be honest.
