clutch drops to the floor when pressed
So I have had my car back from the mechanic for about 2 days, it had sat for roughly 3 years prior to me replacing the engine. I have been driving with no issues for about 300 miles. I went on break at work today and decided to run to the store for a redbull, was a little difficult to get into gear on the way there, when I left the store I got in and went to start my car and my clutch literally fell when I touched it. Any ideas on what it might be or a quick fix so I can get home?
