Issues with my 2 year old?

Shes just changed so quickly its weird! Her once unbelieveable appetite has shrunk to a few bits of food a day,she will not let anyone hold her apart from me if her daddy or grandparents try and hug her or hold her hand she'll paddy for ages! She wakes at all hours of the night after having her sleeping beautifully for well over a year and all day all she wants to do is sit on me on the sofa and cuddle! Now i know she loves me and i love her too but i have to get off my bum during the day and do the housework go to the toilet etc lol. Also she seems to be scared of men,if i wasnt with her 24/7 i'd worry something had happened to her. I just want my little angel back :( And all these things have just happened over 2 weeks and ive done nothing different to what ive always done with her as far as routine goes. Is this normal and just a phase or does it sound like ive done something wrong?
