Rather than going home or getting an apartment--what about just staying in a cabin in the mountains or a hotel on the beach for a couple of days? If the weather is good then just viewing the sunset or sunrise can be rejuvenating. I think you need to learn to enjoy spending time alone. I have learned to deal with uncomfortable feelings about others by taking time outs. Sometimes those timeouts make us want to be with the people who were making us uncomfortable again. Most people aren't sunshine all of the time. It doesn't have to be a drastic step. Just find a place somewhere that you can get recharged. Sending positive energy your way. Your life is not a waste.
