The pressure of being single

So I'll start off by saying I'm a single 25 year old male. I spent Christmas with my immediate family and some relatives (my mom's side of the family, my parents are divorced). Both my siblings and all my cousins who came to visit are all straight, partnered, and in serious relationships. I'm the token single gay in the family.During our big gathering and being surrounded by so many partnered family not only had me kind of down but also had me starting to feel the pressure of not being with someone. To make matters worse, my sister made the announcement of her engagement and wedding plans for the fall. So the pressure is building even more to not only have a date for her wedding but have someone special by that time. Maybe I'm just tired of being the single one and having to tag along with these couples all the time.My question is: Am I being crazy or are there any of you who are going through anything similar?
