I don't know what to do,what I want anymore and I feel like I've been doing it too much.

Ok so I'm not sure how to start this, I'm 20 this year and I'm an asian,been living with social anxiety until recently I manage to open up myself more. I've ended a 2 years long distance relationship several months ago. The first month I thought I am okay with it,didn't had any emotional breakdown or regrets but I finally broke down a month later after finding out he got with another guy within hours after we ended our relationship. During the first month, I went for 2 or 3 hook ups as I've been so sexually deprived for every 6 months and it was all no string attached. But ever since the breakdown, I went on a rampage and slept around a lot almost every week once. At one point I had 2 hookups every single week for 3 weeks straight. I seems to have also put emotion and feelings into these sex dates but of course it didn't turn out anything at all cause all they are looking for are no string attached and it somehow upset me most of the times. I did try to stop this activity and delete hookup apps like Grindr and Planet Romeo in hopes I would find someone worth it and after 2 weeks,I found this guy on Tinder. We chatted quite a lot and hang out twice. The first date turn out well,we talked a lot and seems to hit pretty well.However, the 2nd date was good but it turn out bad in the end. We had dinner together and he asked if I want to watch some movies back at his place, it was all good until he start cuddle me up and kiss me but every time when I follow up (cuddle and kiss him back) he would start to back out on me. I gave up doing anything after the 3rd attempt and he didn't talk or text me back afterwards. I was so upset afterwards as everything seems to be going well until he back out on me last minute without a reason even though he was the one that initiate and make a move. Now I seems to have gone back to my old ways, I even go for sex dates even though I don't feel like it because I don't like to be alone. I really don't know what to do and if this lifestyle is really what I want. I really just want someone genuine that I can love and be love back like back then and I still regret of what I've done due to my immature ways and behavior that eventually cost my relationship. Most of the time I've been acting fine and very cheerful in front of everyone but inside I felt so depressed sometimes I don't know what am I for. I told my best friend about it and he told me that its nearly impossible to find the right one through this way or let alone a Caucasian guy that's living in Asia looking for a relationship. I tried to open up to other races but it just doesn't seem to interest me or goes well as I've been so attracted to white guys that I don't have any other preference for some reason and this isn't helping me at all as I only limit myself to 1 type of race.
