Swimming or MMA??????

i swim year round (except for august) right now, i practice 5 days a week for 2 hours. I have started to get a lot of muscle and i love to swim. really want to learn how to defend myself/fight. I was thinking about taking kickboxing, jujitsu, and muay thai. Idk if i should try MMA or not. please help!!! and i cant do both at the same time
