New dating anxiety

I started seeing a guy two months ago. We talk everyday,

he's kind of me, we go on dates and spend time together.

But we had a talk the other day and he said he's not sure

if he can handle a serious relationship at the moment

because of how stretched thin he is with work, friends etc

and doesn't want to begin something like that. He still

wants to keep dating each other and says things could

change if he had more time in the next few months. The

uncertainty of your relationship because it's not very

secure gives me a massive amount of anxiety and makes

me feel very depressed. Some days I can't get out of bed

and end up sleeping the whole day and night to try to

avoid the feelings. I don't know how to stop this anxiety

because we still are in somewhat early days and I should

just relax and let things happen naturally, but I don't

know why I feel so anxious. This happens once I start

dating anyone for more than a month and a half. I just

want to feel happy and enjoy the present moment, but

these feelings make it hard to even want to move

sometimes.
