Help I feel antisocial as hell..?

Most of the time I feel like being alone and round things I enjoy by myself but there will be sudden urges that make me feel alone and in need of love like a girlfriend and so I plan to go look for one the next day (this always happens at night or around midnight and when I wake up I have lost atleast 80% motivation and just feel like being alone again. Why do I feel better at night? I hate when it's all sunny out. Maybe because it's hit as hell here right now! Average 100 degrees
