Ocd / autism?

Hi all I am a freshly 21 yr old girl, not diagnosed with autism, I do have OCD, I have had ocd since i was 12. I have been learning more about autism and I cannot tell if I am on the spectrum or if it is just overlap with Ocd traits. So the stuff that feels like potential autism to me is that I was a late talker, I started consistently talking when i was like 23 months old. I knew how to read at FOUR. I have a really high iq, I took it 3 times and I got 149. I have never cared that much about having many friends. I don’t club or party or care about going out, I like being alone! I definitely do like hanging out with other girls sometimes but it just doesn’t feel very important to me the way other people care about a social life. I eat the same things everyday. I eat extremely healthy but I do not have a variety of meals, it is whatever I currently have decided is the favourite. (I think this is a big one that made me wonder if I am on the spectrum, cause if I am talking to someone about “meals to cook”, I am thinking.. I literally eat the same thing everyday.. and don’t know what to say lol). Oh also I only go to the same 2 cafes I like for coffee. My OCD is extremely numbers related. Certain numbers are safe certain ones have to be avoided. I have to turn on lights usually a few times til it ‘feels right’. 😣 I hate my ocd its really annoying. I do have a good job, i have a part time job too, I live alone and provide for myself, I feel like my romantic life is very much the same as other girls, I drive, I workout everyday, I am definitely a high functioning person. Whenever i spoke to a doctor about this I was told I have ocd
